A medieval tower built in 1392, standing at the entrance to the bay and the boat harbor, and considered a symbol of the city. In the past, it was part of the city walls, like other towers in the city. The tower has a unique square structure, with a protruding upper section, and on one of its walls is an 18th-century fresco featuring the emblem of the Republic of Genoa. Inside the tower, one can find memorabilia from the Republic’s fleet. The tower, as well as the square where it stands, is named after the navigator born in the city, who joined Ferdinand Magellan, the first to circumnavigate the globe.
