比萨斜塔位于意大利托斯卡纳省比萨城北面的奇迹广场上，是一组古罗马建筑群中的钟楼。这座堪称世界建筑史奇迹的斜塔，不仅以它“斜而不倒”而闻名天下，还因为1590年意大利伟大的科学家伽利略曾在斜塔顶层做过自由落体运动的实验而更加遐迩闻名。每年有80万游客来到塔下，为自己能亲眼目睹这一由缺陷造成的奇迹而庆幸万分。
比萨斜塔是比萨城的标志，是意大利优秀的古代文化遗产，被誉为中世纪七大建筑奇迹之一。1987年它和相邻的大教堂、洗礼堂、墓园一起因其对11世纪至14世纪意大利建筑艺术的巨大影响，而被联合国教育科学文化组织评选为世界遗产。
The Leaning Tower of Pisa or simply The Tower of Pisa is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the cathedral and is the third oldest structure in Pisa’s Piazza del Duomo (Cathedral Square) after the cathedral and the baptistry.
The Tower of Pisa is the bell tower of the Cathedral. Its construction began in the august of 1173 Although intended to stand vertically, the tower began leaning to the southeast soon due to a poorly laid foundation and loose substrate that has allowed the foundation to shift direction. The tower presently leans to the southwest.The bell-chamber was not finally added until 1372. In 1987, the tower was declared as part of the Piazza dei Miracoli UNESCO World Heritage Site along with the neighbouring cathedral, baptistery and cemetery.
