From the Turkish Daily News comes this tantalizingly vague item:

The remains of an ancient port appeared on a shore in the Aegean town of Burhaniye when the seawater withdrew due to seasonal tides.

The 2,500-year-old port remains are part of the ancient city of Adramytteion, experts said. Hasan Sezer, a local of Burhaniye, said the remains appear at the same time each year. "When you row around, you feel like a part of history," said Sezer. "We must preserve our historical heritage."

Excavation work has been ongoing in the ancient city of Adramytteion for 20 years. The work focuses on a big change, which dates back to 500 B.C., and the necropolis that belongs to it.

Among the important findings so far are pieces of frescos, and a mosaic of a peacock on a wall. Most findings are exhibited at the Ă–ren Open Air Museum.

... I'd love to hear/read more about this; all I previously knew about Adramytteion was that they minted coins (including at least one coin with the face of Zeus in 3/4 view, which strikes me as not very common)...
