The Leaning Tower of Pisa is one of the world's most famous landmarks and is often referred to by several other synonyms. Some call it the Tower of Pisa, while others refer to it as the Leaning Tower or the Bell Tower of Pisa. Some even refer to it as the Campanile di Pisa or the Torre Pendente di Pisa, which are the tower's names in Italian. Regardless of how it is referred to, this architectural marvel leans at an angle of 3.97 degrees and attracts millions of tourists every year. The leaning factor has been corrected over time, but it still remains one of the most famous monuments in the world.
