Ballinderry Parish Church, Lower Ballinderry Road, Ballinderry, BT28 2NL

Ballinderry Parish Church is a Church of Ireland building constructed in 1824, situated on the north side of Lower Ballinderry Road in Upper Ballinderry. The church is built of roughly squared rubble stone laid to courses with projecting chamfered ashlar sill bands. It is rectangular on plan, aligned east-west, and has a pitched natural slate roof with raised stone verges. Cast-iron u-profile rainwater goods are supported on a corbel table.

The church is fronted by a three-stage square tower at the west end, topped with a slender octagonal ashlar spire. The principal west-facing gable is abutted at its centre by this tower, with a blank section to the right and a later lean-to annex to the left. The main entrance is located at the south of the tower's first stage, comprising a replacement double-leaf timber panelled door surmounted by pointed arched timber mock Y-tracery panels, all set within a pointed arched chamfered ashlar surround. The tower's west elevation contains a pointed arched stained glass window in a brick surround with flush chamfered ashlar sill. A later lean-to extension abuts the north elevation, featuring a pointed arched lattice glazed window in a plain ashlar surround with flush chamfered sill.

The tower's second stage displays a diagonal recessed ashlar panel recording the building's construction: "Erected A.D. 1824 by a Donation from the Marquis of Hertford of £1000 and £1200 presented by the Parish Rev James Stannus Vicar. Turtle Bunting and Tho Russell Church Wardens". Square-headed lattice glazed windows open to the north and south in stepped brick surrounds with flush chamfered ashlar sills. The third stage contains louvered openings to the belfry on all sides in brick surrounds, surmounted by a clock face with semi-circular ovolo label mould. A crenellated parapet with plain pinnacles crowns the tower, above which rises the recessed spire.

The nave extends east from the tower, its walls pierced by lattice glazed lancet windows set in stepped brick surrounds with ashlar pointed arched hoodmoulds. Ashlar clasping buttresses with pinnacles project from the nave walls. The north elevation is three windows wide, the window to the right containing leaded stained glass.

A double-height chancel of similar detailing is attached to the east gable. The chancel's east gable features a central stained glass window with reticulated flowing bar-tracery within a stepped ashlar surround. Its north elevation is abutted by a single-storey lean-to extension comprising paired lattice glazed lancet windows to the north and a pointed arched door opening at the east containing a square-headed timber panelled entrance door surmounted by a glazed fanlight, accessed by two stone steps. The south elevation of the chancel is blank. The south elevation of the nave is three windows wide.

The church sits on a substantial site accessed via a tree-lined avenue from Lower Ballinderry Road. The approach is marked by a symmetrical arrangement of square-coursed rubble stone piers with galleted joints supporting a double-leaf cast-iron gate and cast-iron overthrow. The piers are abutted by a plinth wall with segmental coping, supporting cast-iron railings that enclose the site from the road.
