why does the leaning tower of pisa lean
Tower of Pisa leans sideways because it was built on unstable soil. In 1173 construction started on the 180-foot bell tower, which is located in Pisa, a small town in the Italian province of Tuscany. The building began to lean as soon as the first three floors were completed.     Tower of Pisa leans sideways because it was built on unstable soil.
