13 imagesOia is a small town in the South Aegean on the island of Thira (Santorini), in the Cyclades, Greece. Oia was previously known as Apano Meria, a name which still occurs locally as Pano Meria, and the inhabitants are still called Apanomerites. The Ancient Greek Oia was one of the two harbours of ancient Thera and was located in the southeast of the island, where Kamari is now. Oia reached the peak of prosperity in the late 19th and early 20th centuries. Its economic prosperity was based on its merchant fleet, which plied trade in the Eastern Mediterranean, especially from Alexandria to Russia. The two-story captains' houses built on the highest part of the village are a reminder of the village's former affluence. Part of the town was destroyed by the 1956 earthquake. Now Oia is the main tourist attraction at Santorini island.
