Pisa, city, central Italy, in the Toscana (Tuscany) regione. The city lies on the alluvial plain of the Arno River, about 6 miles (10 km) from the Ligurian Sea and 50 miles (80 km) west of Florence. Pisa lay by the sea until the 15th century, by which time accumulated silt deposited by the Arno River had completely cut the city off from the receding shoreline.

The Leaning Tower of Pisa, with its equal helpings of beauty and folly, is one of the most recognizable buildings in the world.
But behind that famous tilt is a fascinating history including plundered loot, treacherous subsoil, hundreds of years of engineering missteps and one proud Italian dictator.
