Lovely place to rest. There are tables arranged outside to the right of the Abbey. Grab some supplies from the shop just up the road in the village, and enjoy the atmosphere. The Abbey is open 24 / 7. Grey Abbey is one of the best examples of Anglo-Norman Cistercian architecture in Ulster, and was the daughter house of Holm Cultram (Cumbria). It was founded in 1193 by Affreca, wife of John de Courcy, the Anglo-Norman invader of East Ulster. The remains, in the beautiful parkland setting of the nearby grand house of Rosemount, consist of the church with cloister and surrounding buildings to the south.

19th-century folly and lookout tower near Bangor. Named after the 5th Baron's mother, Helen. He intended it as a shrine for poems - Tennyson's Helen's Tower is the best known of them. Well worth a stop off to explore the architecture.
