Because it is leaning.

Marcello Pisas was born on 1977-09-04.
The Leaning Tower of Pisa has an inclination of approximately 3.97 degrees. This tilt is the result of unstable foundation soil, which caused the tower to lean during its construction in the 12th century. Efforts have been made to stabilize the structure, reducing its inclination to prevent further leaning. The tower now stands at about 56 meters tall, with its iconic tilt being a major tourist attraction.
