​ENOS (anc. Aenos), a town of European Turkey, in the vilayet of Adrianople; on the southern shore of the river Maritza, where its estuary broadens to meet the Aegean Sea in the Gulf of Enos. Pop. (1905) about 8000. Enos occupies a ridge of rock surrounded by broad marshes. It is the seat of a Greek bishop, and the population is mainly Greek. It long possessed a valuable export trade, owing to its position at the mouth of the Maritza, the great natural waterway from Adrianople to the sea. But its commerce has declined, owing to the unhealthiness of its climate, to the accumulation of sandbanks in its harbour, which now only admits small coasters and fishing-vessels, and to the rivalry of Dédéagatch, a neighbouring seaport connected with Adrianople by rail.
