A single-room, timber-roofed basilica of the 14th century, which, according to historical sources, served as the church of the monastery of Kinsterniotissa. It is located on the north side of the city and is built on a rock, near the now-destroyed Byzantine-era cisterns.
A simple building, coated on the outside, it does not allow us to observe the decoration of its masonry. Only the vault of the sanctuary bears witness to a similar attempt at decoration with the blind arches on three sides. Inside, it preserves frescoes from the second half of the 14th century. The quality of the painting is very good, but it is particularly difficult to study because the frescoes are blackened by soot.
