The small monastery of Agioi Theodoroi lies next to the old katholikon. There is no record of the monastery in byzantine texts, and a few limited mentions to it date to the 17th cent., a period when the new katholikon was founded. It is a domed, two-column cross-in-square church. It is built in isodomic masonry, making use of orthogonal porous blocks. The elegant, 12-sided dome has one deep niche on each side, with one narrow lighting opening. The altar, to the east, is shaped as a triple three-sided apse. A bilobe bell tower rises above the west gate.

The interior wall paintings date to the early 17th cent., reminiscent of the Moschos’ workshop. A large portrait of the founder, Isaias Myraios, along with a founding inscription with the year 1635 can be seen at the templon’s (screen or iconostasis) west side, south of the diaconikon entrance. Various ruined buildings of the monastic complex are preserved: the main gate, an orthogonal two-storey building of the 18th century, two attachments to the church, one of them covering a tomb with an arcosolium and other unidentified remains.
