A forgotten shoreline can be a ruthless editor of human history. When sea levels rose after antiquity, coastal places that once buzzed with trade, ritual, and migration slipped below the waves and out of our stories. Now, an ancient sunken settlement off the Crimean coast of the Black Sea—known as Akra—has been steadily reappearing through underwater archaeology. What scholars are finding there doesn’t just enrich local history; it challenges our sense of how far-flung and sophisticated seafaring societies in the northern Black Sea really were.
