THE WORN MARBLE STEPS
AT THE LEANING TOWER OF PISA
The Leaning Tower of Pisa is a freestanding bell tower whose tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure’s weight. Completed in 1372 after 199 years of construction, the 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.
