John Hancock Tower
This mirrored marvel is Boston's tallest building. During construction, glass windowpanes began to fall off the building, sending 500 pounds of glass plummeting to the pavement below. Completed in 1976 after all 10,344 windows were replaced, the 60-story skyscraper has been considered safe ever since.
Fun Fact: The total amount of glass on the John Hancock Tower covers 13 acres.
