Architecture Facts

The Taj Mahal took 20 years and 20 thousand men to finish!

The World Trade Center towers used to have two zip codes, 10047-10048, one for each building.

Because heat expands the metal, the Eiffel Tower always leans away from the sun.

The word 'attic' comes from Attica, the region around Athens, Greece, where a distinctive architectural style featured decorative columns on upper facades.

Jericho is the oldest walled city in the world at 9,000 yrs old!

One percent of Greenland's population lives in a single apartment building!

Sheikh Hamad, billionaire and royal family member in the United Arab Emirates, had a huge carving of his name that's even visible from space etched into a private island.

In 2007, a woman named Erika La Tour Eiffel married the Eiffel Tower.

Over 10,000 birds a year die from smashing into windows!

There is a basketball court on the top floor of the U.S. Supreme Court Building. It’s known as the “highest court in the land.”

The Gate Tower Building skyscraper in Japan has a highway passing through its fifth, sixth and seventh floors.

Lynnewood Hall is a 110-room palace outside Philadelphia, closed to the public for more than 80 years. It was built for the Widener family. A father and son, George and Harry, boarded the Titanic in 1912 and never came home. Inside were more than 2,000 artworks that later helped found the National Gallery of Art. This fall, for the first time in generations, the doors open. You can walk in.

Instead of McDonald's tearing down a ~230-year-old Georgian mansion, citizens of a small NY town forced them to renovate it instead, resulting in a uniquely historic franchise location.

The Lincoln Memorial has a secret: a 43,800 sq ft cave beneath it - nearly twice the floor space of the memorial above. Rainwater seeping through the marble has grown real stalactites, and 1914 construction workers left cartoon graffiti on the columns, now preserved behind plexiglass. It opens as a public museum for the first time on June 25.

The floor of Hoover Dam's monument plaza is a celestial map. Sculptor Oskar J.W. Hansen embedded 209 brass discs into the terrazzo, each marking a star or planet visible on September 30, 1935 - the night FDR dedicated the dam. It took 200,000 astronomical calculations. If every historical record vanished, a future civilization could read that floor and calculate exactly when Hoover Dam was dedicated.

Justo Gallego Martinez spent 60 years building a full-scale cathedral by himself in Mejorada del Campo, Spain. He had no architectural training, no blueprints, and no building permits. He used recycled junk - stacked oil drums for pillars, bicycle wheels as molds, broken glass for windows - on land he inherited. He died in November 2021, aged 96, with the cathedral still unfinished.

Antoni Gaudi died on June 10, 1926, struck by a tram on the way to his daily confession. On June 10, 2026 - exactly 100 years later - Pope Leo XIV blessed the Tower of Jesus Christ atop the Sagrada Familia, making it the world's tallest church at 172.5 meters. Construction had taken 144 years.

The Great Pyramids of Giza were once covered in polished white limestone blocks so smooth that a knife blade could not fit between them. In sunlight they blazed like mirrors across the desert. In 1303, an earthquake loosened the casing. A sultan stripped the stones to build mosques in Cairo - and the rough stepped core we see today is what was left behind.

Simon Rodia, an Italian immigrant tile mason, spent 33 years building the Watts Towers in Los Angeles entirely by hand - no machines, no scaffolding, no bolts, no welds, no blueprints. His only tools were pipe-fitter pliers and a window-washer belt. The tallest spire reaches 99 feet. When he finished in 1954, he deeded the land to a neighbor, boarded a bus, and never came back.

The Empire State Building's spire was designed as a boarding dock for airships. Passengers would cross an open gangplank 1,250 feet above the street, then ride an elevator down. In September 1931, a small airship docked there for three minutes in 40 mph winds. Two weeks later, a blimp lowered newspapers to the tower on a 100 foot rope. Updrafts made the mast unusable. No airship ever truly docked there.

Those giant wooden castle playgrounds from the 1980s and 90s were designed by kids. Architect Bob Leathers visited local schools, collected children's drawings, and turned them into blueprints. Then the town's own parents and volunteers built it by hand, usually in about five days. He did this in more than 2,000 communities.

This ironworker on the Empire State Building was photographed by Lewis Hine, a man in his mid-50s whose pictures of kids in mills had already helped turn America against child labor. In 1930 Hine climbed the bare steel alongside the crews, and for the highest shots they swung him out in a basket nearly a quarter-mile above Fifth Avenue.

A 43-year-old French postman tripped over a stone on his rural mail round in 1879 and decided to build a palace. Ferdinand Cheval collected stones on his 18-mile route for 33 years - first in his pockets, then a basket, then a wheelbarrow. Neighbors called him insane. He carved into the wall: 10,000 days, 93,000 hours of struggle. 170,000 people a year now pay to see it.

A London skyscraper accidentally became a giant curved mirror. Its glass facade focused sunlight into a beam so intense it melted a parked Jaguar, scorched a shop, and let a reporter fry an egg on the pavement. The architect had built the same flaw in Las Vegas years earlier.
