According to the standard monastic organizational plan – including the attendance of monks at meals in the context of their daily routine – the refectory of the Monastery is physically connected with the old cathedral, and it is entered is via the staircase which starts at the outer nave of the cathedral. The refectory occupies the upper level of a structure which was completed at the end of the 15th century.
In the area below the refectory are the storage rooms of the Monastery, while the stables were at the ground-level section. In that earlier day, the kitchen had been built immediately north of the refectory; it had a classic square plan, was dome-covered, with the hearth in the center, and a central chimney.
