The Hermitage of St. Nile (Osiou Neilou) is where, according to the tradition, St. Nile, the founder of the Monastery of Giromeri, had stayed, is located to the left of the road leading from Filiates to Tsamanta. It consists of a small set of natural cavities in the rock and traces of building activity can still be found. On the outer side of the wall, at the entrance of the caves, a fresco of an Archangel is preserved, while other frescos from the 14th century are also well preserved in the interior. Probably the Hermitage was used as an ascetic hermit space, long before the advent of St. Nile. The access is easy and the pilgrims can pay their respects in the church inside the cave formed at the base of the cliff.
