West of Lessini, there is a single-room aisled church, which is the katholikon of a monastery dedicated to the Virgin Mary. It has undergone many reconstructions and modifications and is associated with events of the revolutionary struggle. According to inscriptions set in the walls, it was originally built in 1595, during the post-Byzantine period, and was renovated in 1781. It is of interest to note that the long southern side of the church is from the renovation phase. There is an ornamental band here running the entire length which arches around the windows and the southern entrance. The repeated motif on it is a four-leafed cross. On the lintel is a relief worked into the stone of a cross and floral decoration of western origin.
Of the remaining buildings of the monastery, the two-storey cells are preserved, which were reconstructed according to an inscription in 1761.
