In the late nineteenth century, repairs were executed by The Office of Public Works (The O.P.W.). Unfortunately, an excessive amount of concrete was used, the crudity of which is still obvious today. The remains of the abbey include the abbey church and some of the conventual buildings, dating from c. 1193 – c. 1250. The original plan of the monastery can be followed with ease through foundations and earthworks. The abbot's seat has been preserved. It is fitted inside a pointed arch and flanked by detached colonettes. Corbel tables are also a rarity in Ireland, but the Cistercians can boast two of them, one at Tintern and one at Grey. At Grey the corbels were inserted when the roof was raised, probably in the early fifteenth century. There are eight of them altogether, carved with oak leaves, human figures and animal heads.
