Paraportiani is probably one of the most prominent churches in the world. The church got its name because it is located near the "paraporti '', ie the small gate of the medieval castle's wall. Basically it is a complex of five churches, with the four forming the basis and the fifth on top as a sort of dome. The four churches that constitue its basis are St. Eustatius, which is the center of the cluster, Saints Anargyroi, St. Sozon and St. Anastasia. Upon them rests the fifth church, which gave its name to the whole building, Panagia Paraportiani. It is said that the original foundation of the first church, that of St Anargyroi, was about the 14th century and the building gradually took the form it has today. With a shape that makes Panagia Paraportiani unique, it is without question one of the most photographed religious monuments.
