Plakidiotissa Monastery, established in 1625 is located in Kallimasia. Its name derived from the stone plates (places) found in the area. It is honored on the same feast day as the Dormition of the Virgin (Tis Panaghias), August 15th. During the horrible massacres of 1822 most of its 600 nuns were slaughtered or deserted the monastery. One of the few who returned, Katafigi Mastroyanakis, found the icon of the Virgin in a miraculous way. Today the monastery has three nuns.
