Leaning Tower of PisaLeaning Tower of Pisa reopened in 2001 after 11 years of repair, costing 27 million dollars. Construction was started on the bell tower in 1173, and the structure began tilting north soon after. The foundation rested on soft soil. Builders tried to compensate, but the tower began to lean in a southern direction. Several other rescues were made, but the building continued to tilt. By 1990 officials feared the building would topple, and they closed the structure to the public. The latest round of repairs seems to have worked. Slowly the workers removed soil from beneath the foundation while applying weights on the other side. Children could read Building History – The Tower of Pisa by James Barter.
