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 Dedeagatch, a neighbouring seaport connected with Adrianople by rail .
