Torre di San Vincenzo, Medieval tower in San Vincenzo, Italy.

The Torre di San Vincenzo is a three-story tower with a square base and stone walls located near the port of San Vincenzo. The structure connects to a residential building on its landward side, where an external staircase once provided access to the entrance.

The Pisans built the tower in the 13th century to watch over and defend the southern coast of the Republic of Pisa. It kept its military role for centuries, including after the area passed to the Grand Duchy of Tuscany. Around the mid-16th century the Medici strengthened its defences.

Inside the tower is a permanent exhibition on its history. On the landward side, the external staircase that once led to the raised entrance, preceded by a drawbridge, has been replaced by a residential building. The walls are plastered after restorations carried out in the 20th century.

The tower stands in the town centre near the port, so you reach it on foot along the streets of San Vincenzo, not across the beach. The ground around it is paved and level. Inside, a permanent exhibition covers the tower's history.

The tower's top terrace with battlements replaced a four-vault roof that existed at least until the end of the 18th century. On the landward side, a later residential building was erected where the external staircase and drawbridge once stood. Inside, a permanent exhibition covers the tower's history.
