This museum is located in Radojkovic palace, whose square tower was built in the 16C to withstand the Turks. Before venturing inside, go through the courtyard and skirt the edifice to see the impressive remains of the Illyrian walls (3C BC) inspired by the Greeks. The museum itself exhibits the results of excavation work carried out in the local Prehistoric cave and in the Roman ruins. Among the museum's most interesting pieces, note the two bas-reliefs of Heracles and the bRoman mausoleum. The upper floor is devoted to life on the island.
