Skyscrapers Facts

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.

William Van Alen hid a 185-foot steel spire inside the Chrysler Building's own crown, assembled in secret. His rival H. Craig Severance had designed 40 Wall Street two feet taller - thinking he'd win. Van Alen raised the hidden spire through the roof in 90 minutes on October 23, 1929. The Chrysler Building jumped to 1,046 feet, the first skyscraper to top 1,000 feet. It held the record for 11 months.

Miami's Freedom Tower was built in 1925 as the city's first skyscraper. From 1962 to 1974, it became a federal refugee center people called the Ellis Island of the South. Hundreds of thousands of Cuban exiles fleeing Castro passed through its doors for medical care, paperwork, and a fresh start. The tower closed in 2023 for a $25 million restoration. It reopened in September 2025, 100 years after opening its doors.

Sears Tower's Ledge lets tourists step onto glass floors 1,353 feet above Chicago's sidewalks. Each box weighs 1,500 pounds, built from three layers of half-inch glass. It's engineered to hold 10,000 pounds. No one leans out a window to clean it. A motor pulls the whole box back on rails, straight into the building, then slides back out over the drop. The boxes are still open every day, right now.
