why does the tower of pisa lean
It is situated behind the Cathedral and is the third oldest structure in Pisa's Cathedral Square (Piazza del Duomo) after the Cathedral and the Baptistery. The tower's tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight.he height of the tower is 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side.
