There are some 27 listed buildings and structures in the AONB, including 14 houses and 4 churches. Examples of the latter include Forkhill Parish Church, St. Joseph’s Roman Catholic Church (Killeavy Chapel), the Church of Ireland Church in Jonesborough and the Roman Catholic Chapel in Lislea. Individual listings include bridges, farm buildings and public houses. Although just outside the AONB, Bessbrook is significant in having complete listings of all buildings in Charlemont Square, College Square and Pondview.
The Ulster Architectural Heritage Society (UAHS) and NIEA maintain a register of buildings at risk which includes Killeavy Castle and one of its gate lodges. Three sites in the Ring of Gullion appear on the Register of Historic Parks, Gardens and Demesnes or its Supplementary Sites listing. These are sites that have been selected as being worthy of protection through the planning process. The sites are at Killeavy Castle where there is an important gate lodge; at Hawthorn Hill which contains mature trees from the early 19th century, exotic trees and a walled garden; and at Forkhill House where the grounds contain interesting ornamental features and ponds. The National Trust’s Derrymore estate is also on the register. The courtyard buildings at Slieve Gullion Forest Park have, in recent times, have been renovated to fulfil new functions, providing visitor facilities to this site, a venue for meetings and a base for the Clanrye training and employment agency.
The villages of the AONB provide local focal points for the provision of housing, social interaction, employment and services. All have experienced growth in recent years and further development within the settlement limits of each village is anticipated.
