Archaeological recording at Quirt Farm, Dwyran, Anglesey during 201617, in advance of renovation works, revealed new details of the former medieval grange chapel attached to the Cistercian abbey at Aberconwy. The grange included the later farm of Quirt whose farmhouse incorporates the nave and chancel of a former medieval grange chapel, an unusual and significant survival which reflects the wealth of the grange and its importance to the abbey. Medieval roof trusses recorded in the 1930s, though no longer clearly visible, are thought to exist above the curved ceiling of the chancel. A large chimney breast was inserted into an assumed chancel arch area between the former chancel and nave in the seventeenth century, probably at the same time as an upper floor. The upper floor was modified in the eighteenth and nineteenth centuries and the roof raised to accommodate an attic storey. Further extensions took place in the later nineteenth and twentieth centuries to the west and north-west of the building.
