Thirasia belongs to Santorini island complex and is opposite of Oia. Its today’s shape is what was left from Stroggili west coast after the volcano's eruption in 1.500 B.C. The imposing natural landscape with impressive geological formations, well preserved folk architecture of houses and churches, the amazing view of Santorini, Palaia and Nea Kameni and the scenic Korfos coast with traditional taverns are the main features of this beautiful but not very popular island. It extends over 9000 sq. m and has a population of 260 inhabitants. Archeologists have found here settlements of later Copper period and Classic period. You can reach Thirasia by boat from Santorini or by sailing boat from Oia.
