Madrid's royal palace spreads over more than 135,000 square metres and 3,418 rooms, the largest in Western Europe. Its two leaning office towers were the first inclined skyscrapers in the world, tilted, by the city's own measure, 14.3 degrees. Its granite arch of 1778 was, according to the same tourist board, the first triumphal arch raised in Europe since Rome fell. Its bullring seats 23,798.
Every fact below is sourced twice and hedged exactly where the sources hedge. For the sights themselves, see our guide to things to do in Madrid; for the rest of Spain, start at the country hub.
1. Madrid Has the Biggest Royal Palace in Western Europe
The Royal Palace of Madrid spreads over more than 135,000 square metres of floor space and holds 3,418 rooms, which makes it the largest palace in Western Europe (as of 2026).
The Spanish royal family does not actually live in it. Patrimonio Nacional runs the place as a ceremonial residence and opens the state rooms, the armoury and the old royal kitchen to anyone who joins the queue, while the king sleeps well outside the centre.
2. Its Triumphal Arch Came Before the Arc de Triomphe
According to Madrid's official tourist board, the Puerta de Alcalá, inaugurated in 1778, was the first triumphal arch built in Europe after the fall of the Roman Empire, and a forerunner of the Arc de Triomphe in Paris and the Brandenburg Gate in Berlin.
Sabatini's granite gate no longer marks the edge of anything. Traffic swirls around it where the city wall once ran, and the arch has quietly become the shape Madrileños reach for whenever they need a shorthand for home.
3. The World's First Leaning Skyscrapers Stand Here
The twin Puerta de Europa towers lean towards one another above the Paseo de la Castellana, and were the first inclined skyscrapers in the world; the city puts the tilt at 14.3 degrees.
The slant is not a trick of the eye. Because every floor sits slightly off the one beneath it, no two are quite the same shape, and some of the lifts stop partway up before the geometry defeats them.
4. Spain's Largest Bullring Seats 23,798
Las Ventas holds 23,798 spectators around a ring 60 metres across, which makes it comfortably the largest bullring in Spain, though sources disagree on its world ranking: the city puts it third behind Mexico and Venezuela, while the regional government that owns it calls it second behind Mexico (as of 2026).
It rewards a look even when nothing is on. The neo-Mudéjar brickwork and ceramic panels make the building read less like a stadium than a piece of revivalist architecture that happens to have a sand circle in the middle.
5. Goya Is Buried Beneath a Ceiling He Painted
Francisco de Goya painted the dome frescoes of the Ermita de San Antonio de la Florida, finished in 1798, and his remains have rested in that same chapel since 1919.
It is a strange and rather moving thing to stand under. The saints and onlookers crowding the cupola were modelled on ordinary Madrid faces rather than idealised ones, so the painter lies beneath a ceiling full of his neighbours.
6. Cervantes Was Lost Under Madrid Until 2015
Miguel de Cervantes was buried at the Convent of the Barefoot Trinitarians in 1616, his remains were shifted during a rebuilding in 1673 and then lost, and forensic scientists identified them again only in 2015.
The convent sits in the Barrio de las Letras, the writers' quarter, on a street named after the man who lost him for so long. A monument inside the church now marks where he lies, and it can be visited.
7. An Egyptian Temple Stands in a Madrid Park
The Temple of Debod was begun in the early 2nd century BC south of Aswan and given to Spain by Egypt in 1968 in thanks for Spanish help saving the monuments of Nubia, then rebuilt in Madrid between 1970 and 1972.
It was dismantled block by block and shipped across the Mediterranean before being put back together in the Parque del Oeste. The reward for the city is one of the great sunset spots in Europe, with sandstone in the foreground and the sierra behind.
8. A Metro Station Has Sat Frozen Since 1966
Chamberí station, part of the first Metro line opened in 1919, closed to the public on 22 May 1966 because its platforms could not be lengthened, and reopened as a museum on 25 March 2008.
What survived is the point. The ceramic advertising panels, the ticket windows and the period fittings were simply sealed in and left, so the station is less a reconstruction than a room the city forgot to redecorate.
9. A King Paid for the Metro Out of His Own Pocket
The Madrid Metro was inaugurated on 17 October 1919 by King Alfonso XIII, who had put 1.45 million pesetas of his own money into the scheme when it ran short of funds.
The royal stake was not merely symbolic; the project had stalled and needed rescuing. The king and queen turned up for the opening, and the network they launched has been burrowing outwards under the city ever since.
10. The Oldest Thing in Madrid Is a 9th-Century Wall
The Muslim wall raised when Madrid was an Islamic frontier fort is probably the oldest surviving construction in the city, and a stretch more than 120 metres long still stands in the Parque del Emir Mohamed I (as of 2026).
It is easy to walk past. The remains sit below the cathedral on the slope down towards the river, flint and limestone blocks with square towers, marking the edge of the fortress town that everything else in Madrid grew out of.
11. The Cathedral Took 110 Years to Finish
The foundation stone of the Almudena Cathedral was laid in 1883 and the building was not consecrated until Pope John Paul II did so on 15 June 1993, 110 years later.
The delay shows, and pleasantly so. The exterior keeps a sober classical face that answers the palace opposite, while the interior went its own way entirely, with brilliantly coloured modern ceilings and glass that look nothing like the outside promises.
12. 237 Balconies Look Down on Plaza Mayor
Plaza Mayor measures 129 by 94 metres, and 237 balconies overlook it from the buildings that enclose the square.
Those balconies were the point of the design. The square was built as an arena for public spectacle, and the apartments around it were effectively boxes in a theatre, which is why the whole thing still feels like a room with the roof taken off.
13. Its Biggest Park Is Five Central Parks Wide
The Casa de Campo covers 1,722.6 hectares, about five times the area of New York's Central Park, and was handed to the people of Madrid when the Second Republic arrived in 1931.
It began as a royal hunting estate, which is why it feels less like a park than a piece of countryside that the city never quite absorbed. Much of it is still scrub, holm oak and dirt track rather than lawn.
14. The Retiro Was a Private Royal Garden Until 1868
The Retiro belonged to the Spanish monarchy until the Glorious Revolution of 1868 made it public, and the city now counts more than 15,000 trees inside it (as of 2026).
For much of its life it was somewhere ordinary Madrileños could not go. That history explains the layout, which is a palace garden rather than a municipal one, all formal avenues and follies arranged for a court that has long since stopped using them.
15. A Glass Palace Was Built for a Human Zoo
The Palacio de Cristal in the Retiro was built in 1887 for the Philippines Exposition, an event that included a human zoo, and was inspired by London's Crystal Palace.
The pavilion has outlived the ugliness of its origins and now stands empty by its pond, used for art installations. Knowing what it was built to house makes the emptiness feel less like elegance and more like an apology.
16. A King Founded Its Botanical Garden in 1755
The Royal Botanical Garden was founded on 17 October 1755 by King Ferdinand VI and moved to its present site on the Paseo del Prado on the orders of Charles III, opening there in 1781.
The move was deliberate city-building. Charles III wanted a quarter of the capital given over to the natural sciences, and the garden was planted beside the museum and the observatory as one part of a single enlightened scheme.
17. Picasso and Dalí Studied at the Same Academy
The Real Academia de Bellas Artes de San Fernando was established by royal decree in 1752, once had Goya as a director, and counts Pablo Picasso and Salvador Dalí among its alumni.
It keeps a picture collection that would headline anywhere else and is routinely missed by visitors walking past it towards the bigger museums. Both of its famous students, as it happens, found the teaching intolerable and left.
18. The Prado Shows Only a Fraction of What It Owns
The Prado owns some 7,600 paintings but has displayed only about 1,300 works in its main buildings, with thousands more out on loan to other museums and institutions (as of 2026).
The surplus is a consequence of how the collection was formed. It grew out of what the Spanish crown had already bought and inherited, rather than being assembled to fill a museum, so the holdings were always going to outrun the walls.
19. The Prado Opened as a Royal Museum in 1819
The building that is now the Prado opened to the public for the first time in November 1819 as a royal museum, soon renamed the National Museum of Painting and Sculpture.
Villanueva had designed the building for natural science rather than art, which is why the galleries have the long, top-lit halls of a cabinet of specimens. The pictures moved in afterwards and never left.
20. Guernica Only Reached Spain in 1981
Picasso's Guernica stayed at the Museum of Modern Art in New York until 1981, arriving in Madrid that September, and moved to the Reina Sofía in 1992.
Picasso had made the condition explicit: the painting was not to travel to Spain until liberty and democratic institutions had been restored there. Its arrival was therefore read less as a loan returning than as a verdict being delivered.
21. Spain Bought a Whole Museum for 300 Million Euros
The Thyssen-Bornemisza was once the second largest private art collection in the world after the British Royal Collection, and the Spanish government bought 775 of its works for 300 million euros.
The purchase was strategic as much as cultural. The collection covers precisely the periods and schools the Prado and the Reina Sofía between them do not, so acquiring it completed the run along the Paseo del Prado in one transaction.
22. Spain's Most Famous Bust Spent 40 Years in Paris
The Lady of Elche was found on 4 August 1897 and sold to the Louvre within weeks for 4,000 francs; Spain got it back in 1941 and it moved to Madrid's National Archaeological Museum in 1971.
She remains the emblem of Iberian sculpture and of an argument about who owns antiquity. The hollow in her back, which tradition says held remains or relics, is the detail few visitors ever see.
23. A Queen Founded the Archaeological Museum in 1867
The National Archaeological Museum was created by a Royal Decree of Isabella II in 1867 to hold the coin, archaeological and decorative-art collections of the Spanish monarchs.
It was, in other words, assembled out of what the crown had accumulated rather than what archaeologists had dug. The modern redisplay treats the objects as art as much as evidence, with replicas visitors are allowed to handle.
24. There Is a Tropical Garden Inside Atocha Station
The old concourse of Atocha station holds a covered tropical garden of 4,000 square metres, planted with more than 100 species brought from the Americas, Asia and Australia.
When the trains moved to a new hall, the Victorian iron shed was left without a purpose and given over to plants instead of platforms. The result is a humid, green room in the middle of a railway terminus.
25. Its Oldest Grand Station Is Now a Train Museum
Madrid-Delicias opened on 30 March 1880 and is, in the city's own words, the oldest station in Madrid built as a permanent and monumental structure; it now houses the railway museum (as of 2026).
Because the trains stopped coming, the shed survived unaltered while the busier terminals were rebuilt around their traffic. Locomotives and carriages stand where passengers once waited, under the original ironwork.
26. The Opera House Sat Shut for 41 Years
The Teatro Real was opened by Queen Isabella II on 19 November 1850, closed in 1925 after the building subsided, and did not work as an opera house again until 11 October 1997.
For much of the twentieth century Spain's national opera house simply was not one. The building stood on Plaza de Oriente facing the palace, structurally suspect and variously repurposed, while the repertoire it had been built for went on elsewhere.
27. Building the Metro Closed the Royal Opera House
The Teatro Real was declared a National Monument in 1977 and reopened as an opera house in 1997 after nearly seven years of works; Wikipedia attributes its 1925 closure to damage caused by the digging of the Madrid Metro.
Madrid’s own heritage record is more cautious, describing a building in danger of collapse and a rescue that got no further than shoring it up. Either way the tunnels and the opera house were bad neighbours.
28. Cibeles Rides a Chariot Pulled by Two Lovers
The Cibeles fountain was built in 1782 and shows the goddess on a chariot drawn by two lions that represent the mythological lovers Atalanta and Hippomenes, turned into beasts as a punishment.
Madrid has since given the fountain a second job. It is where Real Madrid supporters gather to celebrate a trophy, which means a piece of enlightenment sculpture spends part of its life wrapped in flags and scaffolding.
29. The City Hall Was Built as a Post Office
The palace on Plaza de Cibeles was built as the headquarters of the Spanish postal and telegraph service and has housed Madrid's city council since 2007 (as of 2026).
Madrileños called it the cathedral of communications, and the joke was fair: Palacios and Otamendi gave a sorting office the spires, galleries and white stone of a basilica. The public can still ride up to the viewing gallery at the top.
30. A King Opened Its Best Rooftop in 1926
The Círculo de Bellas Artes was founded in 1880, and its Antonio Palacios building, whose roof terrace gives one of the widest views over Madrid, was opened by Alfonso XIII on 8 November 1926 (as of 2026).
It remains a working arts club rather than a museum, with a café, cinema and exhibition halls below the terrace. The rooftop looks straight down the length of the Gran Vía, which is the view people climb for.
31. A Cable Car Crosses the City to the Woods
The Teleférico de Madrid opened in 1969 and runs 2,457 metres from the Parque del Oeste over to the Casa de Campo, a crossing that takes about eleven minutes.
It is a genuinely odd piece of transport, a mountain lift installed in a capital city with no mountain. The compensation is the angle: you get the palace, the cathedral and the river from above, without climbing anything.
32. Cutting Gran Via Erased 15 Whole Streets
Driving the Gran Vía through the old centre made 15 streets disappear outright and altered 35 more, taking 315 houses and 43 building plots with them.
The scale of the demolition is why Madrileños of the day called the project the great wound. What replaced it was a properly modern boulevard, and the argument about whether the trade was worth it has never entirely stopped.
33. Spain's First Skyscrapers Went Up on Gran Vía
The city credits the Gran Vía with bringing the country's first skyscrapers, built as American architectural fashions reached Spain in the early twentieth century.
The street reads as a catalogue of that moment. Its towers, domes and setbacks were borrowed wholesale from Chicago and New York, then executed in Spanish stone, which is why the Gran Vía looks simultaneously imported and unmistakably Madrid.
34. One Tower Was Briefly the Tallest in Spain
The Edificio España, built by the Otamendi brothers and finished in 1953, stands 117 metres tall and was the tallest building in Spain until the neighbouring Torre de Madrid overtook it (as of 2026).
It was beaten by its own architects, working a few steps away on the same square. The building spent years empty and half-abandoned before being brought back into use, its stepped brick front now restored above Plaza de España.
35. Its 1950s Tower Aimed to Be a Concrete Record
The Torre de Madrid measures 142 metres, was constructed between 1954 and 1957, and was conceived to be the tallest concrete building in the world at the time of its completion (as of 2026).
The ambition says a good deal about the era that raised it. Spain was largely shut out of Europe and building upwards on Plaza de España was a way of announcing modernity to an audience that was mostly domestic.
36. A World Cup Built Madrid's Concrete Needle
Torrespaña, the 220-metre broadcasting tower Madrid calls El Pirulí, was inaugurated in 1982 to carry the television signal of the World Cup held in Spain.
The nickname means lollipop, which is about right for the bulge near the top. It is not open to visitors, but it is visible from much of the eastern half of the city and has become an accidental landmark for navigation.
37. Spain's Tallest Tower Stands on a Football Pitch
The four towers of the Cuatro Torres Business Area rose on Real Madrid's former training ground, and the tallest of them, César Pelli's Torre de Cristal, reaches 249 metres (as of 2026).
Selling the old sports city paid for a good deal of football, and the skyline changed as a result. The cluster sits at the northern end of the Castellana, far enough out that the historic centre keeps its low horizon.
38. The Bernabeu Opened in 1947 and Still Grows
The Santiago Bernabéu was inaugurated on 14 December 1947 and, after a rebuild finished in late 2024, seats 83,186, though the city describes it more loosely as holding more than 80,000 (as of 2026).
The latest work wrapped the old bowl in a steel skin and put a roof over it, turning a stadium into a year-round venue. The pitch itself can be withdrawn below ground when something other than football is on.
39. A Chocolate Shop Has Poured Since 1894
Chocolatería San Ginés opened as a restaurant and inn in 1890, began serving chocolate con churros in 1894, and now stays open twenty-four hours a day (as of 2026).
Its trade was built on people leaving the theatres nearby, and the pattern has survived every change of fashion since. The clientele at dawn is a mix of those who got up early and those who never went to bed.
40. Its Flea Market Is Named After a Blood Trail
El Rastro means the trail, and the market probably owes its name to the blood left along the street as slaughtered cattle were dragged from the abattoir down to the tanneries.
The street it runs along is still called the riverbank of the tanners. On Sunday mornings the whole slope fills with stalls, and the neighbourhood turns into the closest thing Madrid has to a weekly festival of junk.
41. A Princess Founded a Convent Here in 1559
Joanna of Austria founded the Descalzas Reales as a convent of Poor Clare nuns in 1559 and was buried there; it is still run by Patrimonio Nacional, and her sister María, the widowed empress, died inside in 1603.
Because it took in royal and noble women who arrived with dowries, the enclosure filled with art. Behind a plain façade on a small square sits a painted staircase and a collection few visitors know is there.
42. One Museum Is Just a Painter's Own House
The Sorolla Museum occupies the house and workshop Joaquín Sorolla built for himself, and the city calls it one of the most complete and best preserved artist's houses in Europe.
The studio has been kept as he left it, brushes and easels included, and the garden he designed still screens the building from the street. It is the rare museum where the container explains the contents.
43. Madrid Keeps One of the Few Panda Collections
The Zoo Aquarium opened in the Casa de Campo in 1972 and is one of the few zoos in the world that keeps giant pandas, a line that began when China presented two of them to the King of Spain in 1978 (as of 2026).
The gift was diplomacy as much as zoology, arriving as Spain rebuilt its foreign relationships. The descendants of that arrangement are still the animals people come through the gates to see.
44. Parliament's Lions Were Cast From Captured Guns
The two bronze lions guarding the entrance to the Spanish parliament were cast from cannons captured in the African War of 1860.
They are the best-known animals in Spanish politics and have acquired nicknames, opinions and a good deal of satire over the years. The metal in them is a reminder that the building's dignity was paid for out of a war.
45. One Library Gets a Copy of Every Spanish Book
The National Library was founded by Philip V in 1711, and the letters patent he granted obliged printers to send it a copy of every book printed in Spain, a rule its Recoletos building has applied since opening in 1896.
That single obligation is why the collection is what it is. Nobody had to decide what deserved keeping; everything published simply arrived, which over three centuries produces a record of a country's mind rather than its taste.
46. A Whole Country Eats Grapes Under One Clock
The clock on the Casa de Correos in Puerta del Sol was inaugurated in 1866 by Queen Isabella II, and now strikes the twelve chimes at which Spaniards eat twelve grapes on New Year's Eve.
The ritual is national but the timekeeping is local: the whole country synchronises itself to this one balcony by television. Getting a grape down per chime is harder than it sounds, which is much of the entertainment.
47. An Air-Raid Shelter Hides Under the Retiro
Madrid was besieged from 1936 until it fell on 28 March 1939, and an air-raid shelter dug in the Retiro survives from that period, though the city says there is no historical evidence it was ever used as one.
Its entrances are easy to miss, hidden under asphalt and metal plates among the trees. The park that reads as pure leisure was, for the length of the siege, part of a front-line city.
48. A Marquis Built His Palace to Become a Museum
The Marquis of Cerralbo, who died in 1922, conceived his Madrid palace from the outset as both a home and a museum, and left the collection to the nation on condition it stayed together.
That condition is why the house feels unlike anywhere else. Nothing has been thinned out or rehung to modern taste, so the rooms remain as densely furnished as an aristocratic family actually lived in them.
49. The Guardians of Spanish Have a Motto About Fire
The Real Academia Española was founded in 1713 and took as its emblem a crucible over a flame with the legend Limpia, fija y da esplendor, and the building it works in opened in 1894 in the presence of the boy king Alfonso XIII.
The motto claims the language is refined the way metal is. Each academician holds a seat labelled with a letter of the alphabet, a conceit that makes membership sound less like a job than a place setting.
50. The Inquisition Sentenced 117 People in One Square
On 30 June 1680 the Plaza Mayor hosted a major auto-da-fé at which the Spanish Inquisition sentenced 117 people before a large public audience, twenty-one of them to death by burning.
The square had been designed for exactly this kind of assembly, with the balconies serving as seating and the royal family watching from the bakery building. It is worth remembering while queueing for a table on the same paving.
Where to Go Next in Madrid
Facts are a good way to decide what to actually go and look at. Our guide to things to do in Madrid works through the museums, palaces and parks these claims keep pointing at, and the wider Spain hub collects the rest of the country.
How We Checked These Facts
Every claim on this page carries at least two independent sources, and at least one of them is an official or institutional record rather than an encyclopedia: the Ayuntamiento de Madrid's tourism service and its heritage catalogue, the Comunidad de Madrid, and the museums themselves, alongside reference works. For each source we record the sentence it actually states and the date we read it, then re-fetch the page to confirm that wording is still there. Where a source hedges, we hedge with it. If a register calls a claim disputed, or two official bodies disagree with each other, this page says so rather than quietly printing the tidier version.
FAQ: Interesting Facts About Madrid
Why is there an Egyptian temple in Madrid?
The Temple of Debod was begun in the early 2nd century BC south of Aswan and given to Spain by Egypt in 1968, in thanks for Spanish help saving the monuments of Nubia. It was dismantled, shipped across the Mediterranean and rebuilt in Madrid between 1970 and 1972, in the Parque del Oeste, where it still stands above the city.
Where is Cervantes buried?
Miguel de Cervantes was buried at the Convent of the Barefoot Trinitarians in 1616. His remains were shifted during a rebuilding in 1673 and then lost, and forensic scientists identified them again only in 2015. A monument inside the church in the Barrio de las Letras now marks where he lies.
Is there really a ghost station on the Madrid Metro?
Yes. Chamberí station, part of the first Metro line opened in 1919, closed to the public on 22 May 1966 because its platforms could not be lengthened to the new standard. It was sealed with its ceramic advertising panels and fittings intact, and reopened as a museum on 25 March 2008.
How big is the Royal Palace of Madrid?
The Royal Palace of Madrid spreads over more than 135,000 square metres of floor space and holds 3,418 rooms, which makes it the largest palace in Western Europe. The Spanish royal family does not live there; it is run as a ceremonial residence, with the state rooms open to visitors.
What is the oldest building in Madrid?
The Muslim wall raised when Madrid was an Islamic frontier fort is probably the oldest surviving construction in the city. A stretch more than 120 metres long still stands in the Parque del Emir Mohamed I, below the cathedral on the slope running down towards the river.
Why do Spaniards eat twelve grapes at New Year?
The tradition is timed to the clock on the Casa de Correos in Puerta del Sol, which was inaugurated in 1866 by Queen Isabella II. It strikes the twelve chimes at which Spaniards eat twelve grapes on New Year's Eve, and the whole country synchronises itself to that one balcony by television.
Is Goya buried in Madrid?
He is. Francisco de Goya painted the dome frescoes of the Ermita de San Antonio de la Florida, finished in 1798, and his remains have rested in that same chapel since 1919. The saints crowding the cupola were modelled on ordinary Madrid faces rather than idealised ones.
