While being in the island, it is worth visiting the castle of Skaros. When the Venetian leader Markos Sanouthos conquered the island in 1207, he raised the flag on the castle. It was then that Thira became known as Santorini. The castle guarded the western entrance from attacks. The castle had two portions, one called Rocka and the other where Roman nobles and Catholic bishops had their residence. The castle was never defeated during the 600 years if its existence.Because of its proximity with Fira, it is connected with a public road or by an old path, offering a tremendous views as you walk along the rim.
It is only a 20-minute walk and one that must be on your itinerary. Taverns, restaurants, bars, hotels and rooms to rent are plentiful in Imerovigli.
Tou Christou Ta Thermi
Black pebbles and pumice, red volcanic rocks and geothermal springs at the ruined baths that used to offer a natural SPA! If you come across this beach as you sail around the Caldera, you will be impressed by the small church of Hristos ta Thermi (Christ at Thermi), which is built inside the volcanic rocks, next to the ruined rock-hewn houses. To get there on foot, follow the cobbled road and then the path starting below the “Ta Thermi” pizzeria, near Megalohori village.
