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.

Right in the centre of Fira, this museum gives proper context to all the ruins you’ll see around the island. Most of the finds come from Akrotiri, the ancient town buried by the volcanic eruption: wall paintings, pottery, tools, and other items from thousands of years ago that somehow survived. It’s small, doesn’t take long to get through, and is absolutely worth popping into before or after visiting the Akrotiri site itself.

Saarbrücken's history museum, neighbouring on the Saarbrücken Castle, presents the turbulent history of the French-German border area with special emphasis on the era following the Franco-Prussian war of 1870–71, through various permanent and temporary exhibitions.
