The Monastery of St. Nicholaos Anapafsas is situated very near Kastraki village. It is the first monastery one can meet on the way from the village to Meteora. All around you will see the ruins of other monasteries of Prodromos, Aghia Moni and Pantokrator and the small church of Virgin Mary of Doupiani. The rock, where the monastery stands, is very small and narrow at the top. The main church of Agios Nikolaos Anapafsa is known for its well-preserved wall paintings, made in 1527 by the renowned Cretan painter Theophanis o Kris.
