The chapel of Bet Maskal has been excavated in a bulge in the northern wall of the Bet Maryam courtyard. It is a broad gallery of 11 m. length and 3.4 m. width. A row of four pillars divides the space into two aisles spanned by arcades. The doorways show imitation of monkey-head framework. Beams of light deflect downwards into the chapel from two windows, one of them having a swastika design through which is pierced a Greek cross, while the sanctuary window opening has a Maltese cross motif. A frieze of arches between two projecting horizontal courses finishes the facade on top.
