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.

A trip to Santorini wouldn't be complete without a wine-tasting tour. The island's volcanic wine is particularly renowned for its crispy flavour. Santorini Wine Adventure is based in Fira and offers tours to explore local wine, food and culture, as well as the picturesque countryside.

This impressive domed building houses one of the largest collections of Impressionist paintings in Europe, along with the best Welsh art. The museum also comprises an archaeology and geology collection as well as a natural history exhibit with giant skeletons of whales and dinosaurs.
