The settlement of Ancient Thera, located on Mesa Vouno, 396 meters above sea level, was founded in the 9th century B.C. by Dorian colonists whose leader was Theras. The town was inhabited until the early Byzantine period. The preserved ruins belong to the Hellenistic and Roman phases of the city. The residential area and a large part of the cemeteries were excavated by German archaeologists between 1895 and 1902. The remaining cemeteries on the slopes of Sellada were excavated by N. Zapheiropoulos in the years 1961-1982
