Akrotiri was one of the fortified castles of the island during the medieval years. After Santorini was occupied by the Turks, the strong Venetian castle was torn down. The remains of its towers are easily discernible. The old churches of Aghia Triada and Ypapanti tou Soteros are found in the area. Visit Akrotiri excavations, the site of an Ancient Minoan City, with its wonderful preserved houses and wall paintings.
In Akrotiri you can have your lunch at splendid tavernas built into the rock. A small traditional boat can take you to Red Beach and White Beach as well as to the Volcano.
