Panagia Eikonistria is the most holy site of the island since the miraculous icon of Virgin Mary (Panagia) was found here around 1650. An important intellectual figure of the island and of the Church, Dionysios the Old, was a monk in this monastery. The "Katholikon" of the monastery (its church) which is honoured on the day of the Presentation of the Virgin Mary each year, is a basilica of one aisle with a dome, built in the 17th century. All the church has been painted with hagiographs but the smoke from the many candles has caused extensive damage.
