Decorated stonework at Cistercian foundations is usually modest and simple. This entrance, however, is marked by four pointed arches or ‘orders' carved with distinctive Early Gothic 'dog tooth' decoration dating from 1220-30. 

Above the main doorway is a small window inserted in the 15th century and a miniature bell turret, added when this part of the abbey was re-used as a parish church in the 17th century.
