Ceramic fragments from the 5th-4th century BC have been found in the Potamya inlet south of the village, as well as anchors and metal casing of an ancient ships. The village was first mentioned in an Ottoman document in 1496; the population then consisted of only 16 Christian families, as the attacks of sea pirates had forced many to move to inland Strandzha. According to Austrian diplomat Wenzel von Bronjar who sailed near the village, in 1766 it had 17 houses and its population mainly engaged in wood export. According to another westerner, Enelholm, in 1824 it had 30 houses and was located somewhat inland, with only its pier on the coast. Again, the low population and the location is explained by the attacks of the Caucasian Laz pirates.
