About Akra — Submerged City at Naberezhne Village (Cimmerian Bosporus)
Akra, the 'citadel' Greek city at Cimmerian Bosporus, now 3–4 m underwater at Kerch Strait off Naberezhne village. Distinct from other Bosporan submerged harbours already in batch, Akra preserves 120 m harbour mole at –3 m with tower bastion 8 m diameter, submerged street grid 200×150 m at –3.5 m and defensive wall at –4 m mapped 2011–2018 Institute of Archaeology Moscow State (Blavatsky & Kuznetsov) underwater excavations. Founded by Milesians or Pantikapaians early 6th c. BCE as Strait toll station controlling Cimmerian Bosporus deepwater channel, Akra was Bosporan customs post until 3rd c. CE Goths. Transgression drowned Akra c. 4th c. CE (3–4 m). Wall towers show Nymphaion-style ashlar.
Why it mattersAkra is type Bosporan drowned polis: entire city plan preserved under Strait; mole and grid prove Bosporan harbour urbanism and Strait 3–4 m Holocene transgression model type-site for Black Sea sea-level.
