As beautiful and unique as Fallingwater is now, it had a lot of problems in the beginning. The gorgeous building was built over water and was constantly in danger of sliding into the water. Because of this, the structure almost earned the nicknames Falling IN Water, Rising Mildew, and even America's Leaning Tower of Pisa. Skylights leaked. Sections sagged. The entire building could have ended up a disaster. Instead, the structure became one of the most unique and most visited in the world. Read the story of the man behind the building, Andrew Lloyd Wright, and how Fallingwater became the beauty it is today.
