Akra (Ancient Greek: Ἄκρα) was an ancient Greek city at the Cimmerian Bosporus. The city is now underwater at the Kerch Strait, near the Naberezhne village in Crimea.^[1][2] It was flooded as a result of the transgression of the Black Sea and is now almost entirely immersed in the sea, with the exception of a small section at the Yanysh lake.^[2]

It was founded in the late 6th BC by Nymphaeum or Panticapaeum and was part of the Kingdom of Bosporus until the beginning of the 4th AD.^[2][3] It was an important place for anchoring and trade.^[4]

The layers of the Roman and the Late Hellenistic periods are destroyed by the waves but the early Hellenistic and Classical periods layers are intact. The city had well-developed fortifications, including walls and towers. The underwater research has revealed many archaeological findings including coins, amphoras, terracottas, buildings and personal objects.^[1][4]
