Museo del Mare

This museum sits inside the Fortezza Spagnola in Porto Santo Stefano.

It’s divided into two sections.

The first documents the work of the ancient boat and shipbuilders. It also displays the tools and instruments they used, as well as models of the different ship parts.

The second is a collection of archaeological treasures. You’ll mostly find stuff of Roman origin, but there are also bits of boats, statues, ceramics and towers found in the waters around Monte Argentario and Giglio Island by divers in the ’80s and ’90s.
