About
About Akra — Eastern Breakwater Spur at Naberezhne (Cimmerian Bosporus East)
Eastern breakwater spur of submerged city Akra at Naberezhne on the Cimmerian Bosporus, where the Milesian port's eastern harbour arm now lies 3–4 m submerged off the sandy bar east of the city island. 2 m and ship ballast pile at –3 m examined by 2016 underwater museum diving and CHAM sonar. Founded c. 575 BCE, Akra was tide-free port until c. 500 CE coastal subsidence drowned island; eastern breakwater shielded easterly Bosporus chop. Breakwater core holds Late Classical stamped tiles.
Why it mattersEast spur proves Akra dual-harbour (west city island vs east spur); stamped tiles date Bosporan public works and bar subsidence.
