Torre del Magnale, Medieval watchtower in Livorno, Italy

Torre del Magnale is an octagonal stone tower that once stood at the entrance of the former Porto Pisano, featuring multiple floors and an observation platform at its summit. Today only foundation ruins remain visible along the Calata del Magnale quay within the modern industrial port.

The tower was built between 1154 and 1163 and served as a crucial defense point and headquarters for the supreme commander of Porto Pisano. Over time it underwent multiple reconstructions, transforming from squared stones to reinforced bricks in its later structure.

The name Magnale comes from the Latin for "great", a reference to the tower's size; it was also called Torraccia. In the Middle Ages the area around it held the customs house, the Domus Magna warehouse and the residence of the maritime magistrates answerable to Pisa's Consuls of the Sea. A plaque placed in 1903 during Pietro Vigo's restoration recorded that the tower welcomed popes, kings and captains.

The site is located within Livorno's modern industrial port zone and can be accessed from the Calata del Magnale quay. Since only foundation remains are visible, wear sturdy footwear and be mindful of ongoing port activities in the area.

A plaque placed in 1903 during restorations promoted by Pietro Vigo, founder of the Livorno State Archives, recorded that the tower was completed in 1163 and hosted popes, kings and captains. Recent Allied aerial footage disproved the claim that retreating German sappers blew it up: it shows the tower still standing but collapsed on one side.
