Housed in the castle’s Umur Bey tower, this museum displays archaeological finds (mostly coins) from nearby Erythrae (now Ildırı), the Bağlararası Bronze Age harbour settlement (tools, a curious stone phallus) and the Roman era (superb gold diadems). Much is made of the attack by Russian Empress Catherine the Great’s navy on 5 July 1770 that wiped out the Ottoman fleet.
