Where if the lowest tower in the world?

The lowest tower in the world is often considered to be the "Tower of Pisa," specifically its base, which is only about 3.97 meters (13 feet) above the ground due to the significant tilt. However, if you're looking for a more conventional structure, the "Torre de Pisa" is sometimes humorously referenced as the lowest due to its famous lean. Ultimately, the classification of "lowest" can depend on the criteria used, such as height above sea level or the point of measurement.
