The particular church is the combination of four temples and it is one of the most important monuments of the island. It has a unique structure that you will not see in any other part of Greece apart from Naxos that something similar exists.
The south and the northwest temples have a dome while the other two are vaulted. The south temple is the largest and oldest. It is a single aisle room with a Kytherian type dome that is based on four Kytherian “imichonia” (=angular conical surfaces). The temple is of Byzantine style, 6.70 x 3.10 m.
It was built in the 13th century and the murals are in three layers (13th and 14th century) depicting hierarchs, martyrs, the Annunciation, the Ascension, the 40 Saints, the Theologian, Saint Theodore, the Transfiguration, St. Dimitri on a horse, the Nativity in, the Crucifixion and the Presentation. The North East temple (Panagia) is single-nave with an arch. It dates back to the 13th century. It has two layers of Byzantine frescoes and two post-Byzantine representations: bishops, prophets, the Annunciation, the Virgin, the Virgin enthroned, Christ and other great high priests. The northern church (St. Nicholas) is again a single-nave with an arch and also dates back to the 13th century. In the inscription you can see the name of the painter, archdeacon Dimitrios from Monemvasia, but the date has faded away with time. Above the altar, there is the depiction of Christ praying and holding an open book. In the main temple, you can see a representation of St. Nicholas enthroned and marshal Theodore on his horse. The northwest church (St. Basil) is again comprised of one room with a Kytherian dome and was built in the late 13th century. In the arch of the main church you will see a depiction of the Assumption while in the south wall of the sanctuary you can see a representation of St. John the Baptist and St. Andrew.
The only entrance is on the west and thus the four churches communicate with each other sequentially.
