Bellgrove, 26 Aghnadarragh Road, Glenavy, Crumlin, Co Antrim, BT29 4QQ

Bellgrove is a derelict, ruinous thatched cottage dating from approximately the 1820s to 1839. It is located on Aghnadarragh Road, Glenavy, near Crumlin, County Antrim. The building appears on an Ordnance Survey map of 1832-3.

The cottage is a single-storey structure built of random rubble basalt with a cement-rendered finish and rendered chimneys of red brick. The main entrance originally faced west. A 1972 survey described the cottage as having three chimney stacks, paired windows to the south of the entrance and at the opposite end of the façade, and two single windows. Windows were plain or had a horizontal division, and the panelled front door was flanked by obscured sidelights, with two sheeted entrances.

The building is now significantly deteriorated. The thatched roof has largely collapsed with grass growing where sections remain. The original entrance arrangement is missing, leaving a wide rectangular opening in the front wall. A coupled window on the south end of the front façade is also missing, again leaving a wide rectangular opening. Three windows to the left of the main entrance are derelict and rotten, and render has fallen from the window and door heads. The central chimney has fallen. Windows on the rear elevation are also derelict or missing, with damage or collapse to the window heads. A gabled two-storey return to the rear has a corrugated asbestos roof.

Bellgrove sits in a rural location, set back from the road along a lane and within a now-abandoned farmyard, with derelict single and two-storey outbuildings nearby. A field lies immediately to the rear. Access to the house and its immediate surroundings is difficult due to a build-up of materials, mud and liquid manure, and overgrowth. The cottage was owned by Mr Nelson Bell in 1974 and was partly re-thatched in 1977; by 1994, the roof was derelict. It was delisted on 13 March 2002.
