List of leaning towers

This is a list of leaning towers.

A leaning tower is a tower which, either intentionally or unintentionally (due to errors in design, construction, or subsequent external influence such as unstable ground), does not stand perpendicular to the ground.

The most famous example is the Leaning Tower in Pisa, Italy.

that modern societies think they’ve solved, or surpassed, despite all the evidence to the contrary".
