Torre del Lazzaretto
The Torre del Lazzaretto is a coastal fortification and was built by Cosimo I de Medici. The goal was to protect the island from pirates. The work lasted several decades and ended in 1624. Over the years, it has undergone various restructuring as a result of attacks and destruction. Today, the tower has a quadrangular shape and is privately owned.
