The central church is dedicated to the [[Theotokos]], St. Mary. A second church, originally called Theoktistos, built into a cave, is now dedicated to St. Nicholas. The chapels are:
:The Chapel of Ss Joachim and Anna, the parents of the Theotokos.
:The Chapel of St John Chrysostom.
These chapels were built in chambers that had been dwellings of monks.
