Building

The refectory to the north of the church is an elongated cross-vaulted hall (c.5 x 20m) with an apse on the east wall (bearing traces of fresco). The window arches and the transversal arch responds of the original north wall (carrying the vaults) were built in brick. The structure was extensively restored in 1965-69: the site was excavated (an hypocaust belonging to a later Turkish bath was found, as well as a later south wall), the west and south walls, the cross-vaults over the three bays, the barrel vault over the east bay and the conch of the apse were rebuilt.
