How much degrees is the leaning tower leaning...... 3.5?

The Leaning Tower of Pisa currently leans at an angle of about 3.97 degrees. This tilt has decreased over the years due to stabilization efforts, as it was once leaning at a much sharper angle of over 5 degrees. The tower's lean is a result of unstable foundation soil, which led to its famous tilt during construction in the 12th century.
