ENOS, a town of European Turkey, in the vilayet of Adrian ople, on the river Maritsa, where its estuary broadens to meet the Aegean sea. Population about 8,000. Enos occupies a ridge of rock surrounded by broad marshes. It was the seat of a Greek bishop, but the Greek population has left and the town is almost completely in ruins, although in 1921 when it was in Greek hands it was largely rebuilt. It long possessed a valuable export trade, owing to its position at the mouth of the Maritsa, the great natu ral waterway from Adrianople to the sea. But its commerce has declined, owing to the unhealthiness of its climate, to the accu mulation of sandbanks in its harbour, which now only admits small coasters and fishing-vessels, and to the rivalry of Dedsa gatch, a neighbouring seaport connected with Adrianople by rail. It is crowned by an old castle of the Genoese Gattelusi. Hellenic remains are not uncommon and there are three fine Byzantine churches near the castle.
