Leaning Tower of Pisa
Guinness World Records

Two German churches have challenged the tower's status as the world's most lopsided building: the 15th-century square Leaning Tower of Suurhusen and the 14th-century bell tower in the town of Bad Frankenhausen. Guinness World Records measured the Pisa and Suurhusen towers, finding the former's tilt to be 3.97 degrees. In June 2010, Guinness World Records certified the Capital Gate building in Abu Dhabi, UAE as the "World's Furthest Leaning Man-made Tower"; it has an 18-degree slope, almost five times more than the Tower of Pisa, but was deliberately engineered to slant. The Leaning Tower of Wanaka in Wānaka, New Zealand, also deliberately built, leans at 53 degrees to the ground.
