The Leaning Tor of Pisa (Mean English: Leaning Tower of Pisa, Italish: Torre Pendente di Pisa) or only Tor of Pisa (Mean English: Tower of Pisa, Italish: Torre di Pisa) it the freestanding of the of the Italish stead of Pisa, known worldwide for its unmeant tilt. The tor is found behind the Pisa Headchurch and is the third oldest building in the stead's Headchurch , after the headchurch and the Pisa . The tilt of the tor began during its building in the H12, owing to an unfit grounding that was too soft on one side to rightfully uphold the building's weight. The tilt grew as building went on until it was finished in the H14. It then went on growing until the building was besteadied by works in the late H20 and early H21. The height of the tor is 183.22 feet on the low side and 185.93 feet on the high side. Before being besteadied between 1990 and 2001, the tor leaned at 5.5 , now it leans only about 3.99 notches.
