Leaning Tower of Pisa, Italy

Engineers stabilised the tower between 1990 and 2001, reducing its lean by more than 40 cm.

The story, as a puzzle

A tower on soft ground.
Work began in 1173 on a cathedral bell tower that started to tilt before it was finished, because its foundations sank into soft ground. Pin it.
