One of the most important sights of Kythira is the cave of Agia Sophia in Mylopotamos, at the west side of the island. According to mythology, the cave was the love nest of Paris and Hellen when they took refuge in Kythira. Experts believe that the cave is very large, but till today only 220 meters are open to visitors.
Once you pass the entrance you come across the temple, painted with rare murals and the church of St. Sophia dated from the 13th century. The stalactites of the cave offer an impressive decoration reaching in some spots the height of 6 meters. The cave was explored and mapped by the famous speleologist Anna Petrochilou.
