2010年7月2日 · Leaning Tower of Pisa has never been straight. Soon after building started in 1173, the foundation of the Pisa tower settled unevenly. Construction was stopped, and was continued only a 100 year later. It then became visibly clear that the Tower of Pisa is leaning, tilting to the south. Since regular measuring of the tower began in 1911, the ...

2025年2月18日 · Leaning Tower of Pisa, medieval structure in Pisa, Italy, that is famous for the settling of its foundations, which caused it to lean 5.5 degrees (about 15 feet [4.5 metres]) from the perpendicular in the late 20th century. Extensive work was subsequently done to straighten the tower, and its lean
