Steeped in history, Santorini has plenty of archaeological sites to visit including the ruins of Ancient Thira, Akrotiri and the Venetian fortress at Pirgos. Santorini also offers unique accommodation, inspired by the distinct Santorinian-style, and on the south side of the island there are beautiful beaches with many beach sports and activities available. On the highest peak of Santorini is a monastery of the Prophet Elijah, where there is a picturesque religious feast on 20 July each year. Famous for its stunning caldera, the volcano and the romantic sunset, Santorini is considered one of the top places to visit in the world. Perched on the edge of steep cliffs, the picturesque villages of Santorini offer great view to the Aegean Sea and the submerged volcano. Apart from the caldera villages with the traditional Cycladic architecture, such as Oia and Fira, there are many sightseeing to visit in Santorini. The most important ancient site is Minoan Akrotiri, a town that was entirely covered by volcanic ash when the volcano of Santorini erupted in about 1,500 BC. Another less-known archaeological site in Santorini is Ancient Thera, located on top of a hill above Perissa and offering breathtaking view.
