It is a notable western Greek area, in part for its ancient housing estate (oikotrofeio). The community consists of the villages Tsotyli, Rokastro and the former village Nea Sparti.
Tsotyli was a mixed village and a part of its population were Greek speaking Muslim Vallahades.[3] The 1920 Greek census recorded 959 people in the village, and 400 inhabitants (100 families) were Muslim in 1923. Historian Apostolos Vakalopoulos wrote Tsotyli had 40 Christian families and 150 Vallahades families.[4] Following the Greek–Turkish population exchange, Greek refugee families in Tsotyli were from East Thrace (5), Asia Minor (17) and Pontus (64) in 1926. The 1928 Greek census recorded 852 village inhabitants. In 1928, the refugee families numbered 86 (339 people).[5]
