The Church of Agios Onofrios , located on a hill near Voulismeni, was the catholicon of a monastery that functioned in the 13th century and probably fell into ruins at the beginning of the 20th century (there are no historical references). The temple is single-bay vaulted and externally formed with three arches with a toothed band and brick arches, and an impressive doorway with two arches ending in a relief flower. The interior has frescoes from the 13th century with depictions from the Gospel (Resurrection of Lazarus, Vaiophoros and Niptir, Platytera, various Hierarchs and Saints) and the rare circle of Saint Onofrios (e.g. Saint Onofrios with the Lion). Around the monastery there are the ruins of the buildings of the monastic complex (cells, warehouses, wells, threshing floor, etc.) arranged in a C shape. The walls of the buildings that had no external openings, apparently functioned as a defensive wall.

The two-aisled church is located in the cemetery of Neapolis and is dedicated to the Transfiguration of Jesus and to All Saints. The northern aisle was the original centre of the church, in contrast to the southern aisle, which is more recent. The murals date back to the late 13th – early 14th century, the most important being the depiction of the Virgin Mary being nursed by Saint Anne.
