Both in the village and around it there are at least ten churches and chapels, excellently preserved thanks to donations from the Associations and all the people of Kastanitsio. It is worth mentioning the churches of Agios Nikolaos in the neighborhood of Pyrgos and Ioannis Chrysostomos in Agianni Square, Agios Georgios higher than the village, where a passable marked path leads, etc.
The last renovation was in the chapel of Agios Theodoros, which is located a short distance on the hill above the Square of the Commander Sot. Kourouni in Mana Nerou with a fantastic view of the village. Also the chapel of Agios Panteleimonas, which the visitor reaches after a passable route through the lush chestnut grove. This is the catholicon of the Monastery of Saint Nicholas of Kontolina, which was "bi-existent" and the Monastery was Stavropegic. It dates from the early 16th century. The monastery was burned by the Turks in 1826.
