Aghaderg Parish Hall, 16 Grovehill Road, Drumnahare, Banbridge, Co Down, BT32 3NF

Aghaderg Parish Hall is a symmetrical, classically proportioned single-storey former school house built around 1825 and located at a rural road junction in the townland of Drumnahare, east of Loughbrickland village in County Down. The building was constructed as the Glebe School by the Church of Ireland and served as a school until the 1950s, when it was converted to use as the Parish Hall in 1981.

The building is rectangular on plan with a catslide extension to the rear. It is constructed of exposed random rubble stone with snecking and no plinth. The hipped natural slate roof features angled clay ridge and hip tiles, with overhanging timber sheeted eaves supported on paired simple timber brackets. Gutters are ogee cast iron with aluminium downpipes. There is no chimneystack. Openings throughout are brick-dressed.

The principal elevation faces south and is symmetrically arranged about a gabled central entrance bay. It has two 6/6 timber sliding sash windows in brick reveals with projecting granite cills to either side of the bay. The gabled bay itself contains a central segmental-arched door opening flanked by windows on either side. The door is a replacement paneled hardwood type, flanked by integral two-pane sidelights with granite cills and a radial timber fanlight above. Cast iron pattress plates are present to the entrance bay. The apex of the gable bears a brick-dressed painted plaque reading "Aghaderg Parish Hall".

The west and east elevations are identical, each having an elliptical-arched recess with brick voussoirs. The rear elevation is abutted by a catslide cement-rendered extension positioned left of centre, which comprises three timber casement windows. To the right of this extension is a single window, and to the left cheek is blank. To the right side of the rear elevation is a window and timber sheeted door with six-pane overlight, mirrored to the left side.

The hall sits on an elevated site above the junction of Aghaderg and Grovehill Roads, opposite the entrance to Aghaderg Glebe, and overlooks Lough Brickland to the south. Access from the lower road level is via rubble stone steps set into a bank and retained by a rubble stone wall. The site is bounded to the rear by a steep bank with several mature native trees.

The building was originally established as the Loughbrickland Glebe School in 1825. According to the Ordnance Survey Memoirs of circa 1837, it was described as a plain stone building with two schoolrooms. The school was maintained by the Church of Ireland, with income provided by the Reverend James Mahon, rector of the parish, the Earl of Clanwilliam, and pupil fees. The curriculum included intellectual education using the Dublin Reading Book and selections from the Old and New Testament furnished by the Kildare Street Society, along with writing and arithmetic. Moral education was delivered by the Protestant curate as patron and visitor, with daily Bible readings. The school had 192 pupils in total, comprising 109 males and 83 females, of whom 83 were Protestant and 9 were Roman Catholic. The master was George Rice, Protestant. The building measured 75 by 20 by 12 feet and was valued at £4 13s in the Townland Valuation of 1828-40, with a rent of £3. By 1859, a teacher's house had been built on the plot, and both buildings were revalued at £9 in Griffith's Valuation, exempted from rates. The teacher, John Parnell, had use of the land as part of his salary. The building was restored as the Parish Hall in 1981.
