Venetian rule in Santorini extended from 1207 to 1580, and the last vestiges of this historical period live in the castles that dot the entire island. Five fortresses can be found in Santorini in Oia, Pyrgos, Emporio, Akrotiri, and Skaros, which have been partly demolished by the earthquakes that shook the island in the 15th and 16th centuries. Skaros is probably the most important and well-preserved among the five castles, built on the peak of the namesake rock to protect the village from pirate attacks. The ruins of the once magnificent fortress can be reached on foot from Agios Georgios church in Imerovigli, connected to Skaros by a 0,5 km walking trail and a long stairway.
