Beltrim Castle, 86 Killymore Road, Gortin, Co Tyrone, BT79 8PL

Beltrim Castle is a detached five-bay two-storey rendered house built around 1780–1820, located to the northwest of Gortin on the edge of an escarpment above the Owenkillew River. The building is L-shaped in plan, facing west, with a multi-bay two-storey rendered return to the north that incorporates fabric from a seventeenth-century bawn.

The main house is roofed in M-profile hipped natural slate with a pitched return terminating in a gable to the east end. Five redbrick chimneystacks serve the main house and four rendered stacks the return, all fitted with replacement terracotta pots. Black clay ridge tiles and lead valleys drain via cast-iron guttering carried on cast-iron drive-through brackets at the rendered eaves and cast-iron downpipes. The external walling is painted rough-cast render throughout, with a section of crow-stepped wall to the northwest of the front elevation and a further crow-stepped wall abutting the north side elevation.

The front elevation is symmetrical with five bays over two storeys. Window openings are square-headed with stone sills and timber sliding sash windows, predominantly eight-over-eight with no horns to both the main house and return. The rear elevation has six-pane timber casement windows, while the north elevation of the return features a variety of timber and steel casement windows, including some horizontally-glazed two-over-two timber sliding sash windows.

The central entrance is marked by an elliptical-headed door opening containing a double-leaf timber panelled door flanked by sidelights with iron glazing bars on timber panels. Above is a lintel cornice with a spoked fanlight featuring iron glazing bars. A concrete step and platform with four further concrete steps lead down to the front gravel area.

The rear elevation is abutted by the return, which features three small window openings to the right side and a more formal arrangement of three bays with eight-over-eight timber sash windows and a pair of double-leaf timber glazed doors at either end of the ground floor. The six-bay two-storey south elevation of the return has a single-bay two-storey entrance bay projection left of centre, with a lean-to section to the east containing a square-headed door opening with a replacement timber panelled door. A lean-to five-bay single-storey extension was added to the left end of the rear north elevation around 2000.

The setting encompasses a large farm with mature woodland, accessed via a long gravel avenue from the south. The rear return is abutted by a single-storey outbuilding, its south wall forming part of the ruined seventeenth-century bawn. A rubble-stone wall projects as a turret with matching gothic stone window and door openings (the latter now fitted with a modern timber door). A pair of taller seventeenth-century towers stand to the right, among the most conspicuous surviving remnants of the site's early fabric. Between these towers spans the rear south elevation of a two-storey outbuilding forming part of the main farmyard to the east.

An extensive range of multi-bay two-storey rendered outbuildings surrounds the farmyard. The southern range has been completely renovated to provide additional entertaining accommodation with an outdoor swimming pool along its south elevation. The northern range is single storey to the yard and two storeys at the rear, with an arcaded front of elliptical arches; two to the left have been infilled with door and window openings, while three to the right remain open. At the northeast end of the yard stands a tall stone wall with an elliptical-headed carriage arch carrying a pair of wrought-iron gates, stone coping, and a carved stone bell-cote with a gothic arch and ball finial.

The principal entrance to the estate is at the top of Main Street, Gortin, where a pair of cast-iron gates on stone piers is flanked by matching pedestrian gates. A modern four-bay single-storey gate lodge stands at this entrance.
