Located within an 1852 commissariat store, the Shipwrecks Museum is considered the finest display of maritime archaeology in the southern hemisphere. The highlight is the Batavia Gallery, where a section of the hull of Dutch merchant ship Batavia, wrecked in 1629, is displayed. Nearby is a stone gate, intended as an entrance to Batavia Castle, which was carried by the sinking ship.

　　Other items of interest include the inscribed pewter plate left on Cape Inscription by Willem de Vlamingh in 1697, positioned next to a replica of the plate left by Dirk Hartog in 1616 during the first confirmed European landing in WA.
