Permanent exhibitions in the Spanish Fortress: "Submerged memories" and Maestri d'Ascia
The Spanish Fortress, the historic center's dominating structure, was a military structure built to defend the small residential center and the port from pirate attacks in the early 17th century. The fortress hosts two permanent museums: the Maestri d'Ascia Museum and the "Submerged Memories" exhibition, which aims to chronicle the underwater archaeological research done in the area. The exhibition space spans two floors of the fortress displaying Roman-era artifacts found in the Tuscan Archipelago.
