The museum which first opened in 1964, is Turkey’s first and only museum specializing in underwater archaeology and was opened to house findings from various excavations at Galidonya, Yassiada, Serce Limani, Seytan Deresi, and the nearby sites of Ortakent and Gokce. The museum houses treasures from every age of occupation from Mycenaean, through archaic Classic and Hellenistic Greek, to Roman and Byzantine - all exhibited in chronological order. Among those items exhibited, are Amphora and other stoneware including bowls, glassware, vases, candles, jewellery, miniature statues, coins and tombstones.The most interesting exhibits are undoubtedly those found on the wrecks. The many handsome amphorae, the black child statues and the statue of the goddess Isis are particularly fine.Also worth seeing are the bronze signs from Gelidonya, the farming implements, the bronze weighing scales and the many bronze coins.

The summer months see many other exhibitions, displays and even concerts taking place in the precincts of the castle. All in all, its historical ambiance, fine museum and interesting exhibitions are something that no visitor to Bodrum should
miss. But if you don't get a chance to check out the interior of the Castle, you can at least observe its nightime beauty against the sunset from Kortan, M&M Bar, Bodrum Cafe, Denizciler Kahvesi, Salvaraga Restaurant, Karada Haban, Halikarnas Disco, or any one of the establishments on Cumhuriyet Caddesi.The Castle is hosting the Bodrum Festival which will be held between 7-15 August. Local and foreign classical, pop and jazz groups, Turkish Music and Folk Music performers will take part during the festival. The photograph and painting exhibitions that will take place there are also not to be missed.
