Mountjoy Presbyterian Church, Castletown Road, Tattraconnaghty, Omagh, Co.Tyrone, BT78 5NX

Mountjoy Presbyterian Church is a detached, double-height Presbyterian church built around 1870, situated on the east side of Castletown Road in a rural setting with graveyards to the north and south.

The church is a single-cell building of rectangular plan with a modern single-storey-over-basement extension to the east containing a minister's room. The principal gable faces west and is abutted at its centre by a gabled porch. Walls are constructed in roughly coursed squared-and-snecked rubble stone with a droved finish, finished with sandstone quoins over a splayed plinth. Pitched natural slate roofs are fitted with blue and black clay ridge tiles and stone verges, with a plain acroter to the west gable apex. Replacement ogee uPVC rainwater goods are supported on a corbel table throughout.

The west gable contains a window at each side of the porch, with a central tripartite gothic window above (the outer windows diminished in height). These are surmounted by a stepped stone bell-cote with a single gothic opening containing the bell, topped by stone offsetting and a plain acroter to the apex. The gabled porch has diagonal buttresses with offsetting and a stone finial to its apex. The porch's gable elevation contains a central gothic double-leaf timber sheeted entrance door in a rebated sandstone surround, accessed by a single stone step with plain cast-iron flat handrail. The left cheek contains a single window and the right cheek contains a gothic double-leaf timber sheeted entrance door in a smooth rendered stepped surround, accessed by concrete steps and ramp with steel handrail.

Windows throughout the nave are lancet windows with leaded lattice glazing and stained glass margin lights, set within stepped droved finish sandstone surrounds with splayed sandstone cills. The north elevation of the nave contains six windows. The east gable has stained glass windows at each side of the extension. The extension is constructed in a similar style to the nave but with modern finishes, including cement roof tiles and plastered quoins. Its windows are gothic timber double-glazed casements. The north elevation of the extension contains ground floor access at the right (via six masonry steps and modern steel handrail) and two windows at the left. The basement contains two square-headed timber sheeted doors at the left and a window at the right. The east elevation contains six windows.

The building is accessed through an entrance to Castletown Road consisting of square coursed rubble pillars supporting replacement steel gates. Pedestrian access from the north is through an entrance with square rendered pillars with pyramidal caps supporting an original cast-iron gate. Parking is provided along the road edge to the west.

Architecturally, the church is simply and robustly detailed with traditional characteristics including diagonal buttresses and a bell-cote. It represents a good example of the Presbyterian church type prevalent in the district. However, a much refurbished interior compromises its overall character.

Historically, a meeting house is recorded on the 1833 map to the north of the present site and is listed in Griffith's Valuation. The first edition Ordnance Survey map of 1905-6 shows the church captioned as 'Presbyterian Church', confirming its establishment by that date. According to Rowan, the church is a "crisp little Victorian church" probably built after 1862, when Reverend John Gilmour became minister. The church remains a building of architectural and historic interest, and has social and cultural importance as a local Presbyterian place of worship.
