The mountain village of Daimonia belongs to the municipality of Monemvasia and is built at an altitude of 100 metres. It has about 320 permanent residents. Until 1940, the village was called Daimoniά, a corruption of the name Lemoniά. From the archaeological findings, which have been discovered near the present village, it is concluded that there was an ancient city north of Plystra, near the coast, with an unknown name. Probably, the city is connected with the ancient Kotyrta, which Thucydides mentions.
The construction of the village in its current location took place during the years of Ottoman rule when the inhabitants came here from many areas. The Lyras family was one of the first to do so. This happened mainly after the destruction of Psara and after the defeat of Kythera by the Turks in 1770.
In the village, with its many natural beauties, visitors can see various churches, such as the Agios Konstantinos chapel and the church dedicated to Panagia (the Virgin Mary) Myrtidiotissa. in fact, outside the parish church, there is a large icon of Saints Constantine and Helen, placed in a special recess in the stone wall of the west facade, covered with glass. A villager dedicated the icon in memory of his wife, Eleni.
