Amasra (from Greek Amastris Ἄμαστρις, gen. Ἀμάστριδος) is a small Black Sea port town in the Bartın Province, Turkey, formerly known as Amastris. The town today is much appreciated for its beaches and natural setting, which has made tourism the most important activity for its inhabitants. In 2010 the population was 6,500. Amasra has two islands: the bigger one is called Büyük ada ('Great Island'), the smaller one Tavşan adası ('Rabbit Island'). It was annexed by the Ottoman Empire after the Siege of Amasra.
