A blocked door led to their quarters in the cloisters west range (16). The piscina (4) in the south wall of the nave was used for washing the vessels from the lay brothers' alter.

Beyond the now vanished screen, in the east part of the church moving towards the high alter you enter the crossing above which a square tower rose (3). The crossing was once furnished with wooden stalls for use by the 'choir' or 'white' monks. The chancel (4) is situated to the east end of the church building above where the high alter stood. You will notice the impressive set of long narrow windows with pointed arches repeated on the north, south and east sides. These are known as 'gothic lancet windows' and were possibly the first ever built in Ireland.
