Bozcaada, known in ancient times as Tenedos, is a small island in the north-east Aegean, about 18 nautical miles south of the Aegean entrance to the Dardanelles and 3.4 nautical miles off the mainland. Covering about 42 square km, it is one of Canakkale province's two island districts and the only district in Turkey without villages.
Vineyards cover about a third of the island, which is known for its wineries and local grapes such as Cavus, Karasakiz and Vasilaki. The town has a Turkish and a Greek quarter.
Bozcaada Castle, on the north-east cape beside the town, was rebuilt under Sultan Mahmud II in the early 19th century. Other sights include the early 18th-century Alaybey Mosque, the Greek Orthodox Church of Kimisis Teodoku and the Bozcaada Museum, and Ayazma is one of the island's best-known beaches.
