Magheragall Parish Church, Ballinderry Road, Magheragall, Lisburn, County Antrim, BT28 2QS

Magheragall Parish Church is a free-standing hall and tower Church of Ireland building in the Gothic Revival style, dated 1831 and built with Board of First Fruits funding. The church stands on an elevated site on the north side of Ballinderry Road, surrounded by cemetery.

The building is rectangular on plan with a three-stage square entrance tower to the west, a later chancel to the east (added around 1900), and a vestry attached to the northeast. The walls are constructed of galleted rubblestone with lime pointing, chamfered sandstone plinth course, and sandstone ashlar quoins. The pitched roof is covered in natural slate with black clay ridge tiles and stone coping to either gable end. Cast-iron guttering on decorative brackets runs along a red sandstone eaves course, with cast-iron downpipes completing the drainage system.

The entrance tower is built in rubblestone with sandstone ashlar clasping buttresses. It is three stages in height, with the upper stage octagonal in plan and surmounted by octagonal stone pinnacles with a crenellated parapet wall concealing the roof. Pointed-headed window openings to the upper stage have chamfered surrounds, hood mouldings on all four sides, and timber louvres. A plain projecting sandstone platband divides each stage. The middle stage features an oculus to both north and south elevations formed in red sandstone. The north oculus contains a modern date stone inscribed "Built/1831/Builder R. Mc Henry/Restored/1992", while an iron clock face appears on the south elevation. A stone lucarne rises from both north and south elevations of the west bay, with feathered stone coping surmounted by a trefoil and containing a lancet opening with leaded coloured light.

The south elevation of the tower displays a pointed-headed door opening with stop-chamfered sandstone surround and hood moulding, containing a replacement double-leaf hardwood door and over-panel. Above the entrance is a sandstone relieving arch with a carved stone plaque reading "This is the / Victory / that over / cometh the / world even / our / Faith". To the west elevation, a pointed-headed lancet occupies the lower and middle stages with sandstone relieving arch, chamfered sandstone surround, hood moulding, and painted Y-tracery with leaded lights.

The nave has three lancet window openings on the rear north elevation, each with chamfered sandstone surrounds, hood mouldings, and leaded coloured glazing.

The chancel, added around 1900, is rough-cast rendered with a gabled form abutting the east gable of the main church. The chancel gable has a pointed-headed breakfront containing tripartite lancet openings formed in chamfered sandstone on a single sill, with decorative stone coping above. The vestry is attached to the north of the chancel and features a catslide roof at a different angle. It has a quadripartite stone lancet window to the east elevation and a door opening to the re-entrant angle. Three decorative stone box tombs are located to the re-entrant angle of the east gable and chancel.

The site is enclosed by a rubblestone wall with cement coping and a pedestrian entrance to the west fitted with steel gates and concrete piers. A modern steel railing to a concrete footpath leads to the entrance tower with concrete steps, steel railings, and a concrete universal access ramp. Stone and marble grave-markers date from the early eighteenth century to the present day and are positioned to the east, south, and west of the church. A parish hall and car park are located to the east.

The church underwent restoration in 1992.
