Everyone's heard of the Leaning Tower of Pisa, but what many don't realize is that there are tons of other famous leaning buildings all over the world - some even more tilted than Pisa's. This list highlights some of the world's most famous unintentionally leaning structures - from ancient Chinese pagodas to 21st-century skyscrapers. You might be surprised to learn what man-made blunders and natural disasters made these towers end up this way.
Millennium Tower - San Francisco, CA
Of all the famous buildings that are leaning, the Millennium Tower takes the cake as the youngest. Completed in 2009, the Millennium Tower in San Francisco has already tilted two inches to the northwest AND sunk sixteen inches. After a lot of finger-pointing, experts determined that this is due to the building's support beams being drilled only 80 feet down into dense sand as opposed to 200 feet down into sturdy bedrock – a measure taken to cut construction costs. Oops.
