Seapatrick Parish Church, Church Square, Banbridge, County Down, BT32 4AA

Seapatrick Parish Church is a large free-standing Gothic Revival stone Church of Ireland church located on the north side of Church Square in Banbridge town centre. Built circa 1834 to designs by William Farrell, the church has been significantly expanded and modified over time: the north transept was added in 1864 to designs by W.J. Barre, a chancel and other additions were incorporated in 1883 to designs by Thomas Drew, and a side chapel was added in 1987 to designs by Gordon McKnight.

The church is set on a north-south axis and comprises a double-height nave with clerestory, transepts (with paired transepts to the west), porches to the east and west, a vestry to the east, and a two-stage square entrance tower with spire to the south. The walling is of roughly coursed rubble stone on a cavetto-moulded stone plinth, with cornices and buttresses in stone. The pitched natural slate roof has profiled ridge tiles, raised stone skews and kneelers with finials to some gables. Cast-iron half-round rainwater goods are mounted on projecting sandstone eaves with brackets.

The south gable elevation is abutted at centre by the square entrance tower. The exposed gable sections are blank and flanked by clasping octagonal sandstone buttresses with square plinths and octagonal pinnacles. Flanking the south gable are lean-to side aisles, the left with a raking buttress, each with a tripartite cusped gothic window.

The tower entrance opens to the east with a depressed gothic-arched timber-sheeted door with ornate cast-iron strap hinges and handle, set in a moulded chamfered ashlar surround with square-headed label mould, decorative diamond label-stops and plain spandrels. Evidence of rubble stonework above indicates a former larger gothic opening that has been infilled. A cast-iron lamp sits above the door. A leaded-and-stained glass lancet with hood mould is positioned at the first stage of the tower on the south elevation; the west elevation is blank. A moulded string course with clock to centre runs between the first and second stages on the south and east elevations, with a blank roundel at the west. The second stage has a louvered lancet with hood mould on all four sides and is surmounted by a cornice. Corner pinnacles surmount clasping octagonal sandstone buttresses rising the full height of the tower. An octagonal stone spire crowns the structure, featuring two levels of diminishing lucarnes on the cardinal points.

Windows throughout are gothic-arched leaded-and-stained glass with bar-tracery in ashlar surrounds, hood moulds and chamfered sills, unless otherwise stated. The west elevation is abutted by a paired transept from the 1860s, itself abutted to the south by a projecting lean-to porch opening westward with a gothic timber-sheeted door with decorative cast-iron strap hinges and door furniture. Two quatrefoil windows sit to the right cheek in ashlar surrounds.

The north elevation features two paired cusped geometric windows and is abutted to the left by the vestry and porch, accessed via two bull-nosed stone steps and a pointed-arch-headed timber-sheeted door with decorative cast-iron strap hinges. The vestry has paired mullioned leaded casement windows to the north. A chimney flue and tall replacement chimneystack are visible on the west wall of the chancel. The gables of the transepts each feature a geometric tracery window.

The north transept, added in 1864, sits slightly lower than the main structure, with corner buttresses and a five-paned geometric window to its gable, plus a cusped leaded-and-stained glass lancet to the west elevation. Stone steps enclosed by metal railings descend to the basement.

The east elevation comprises four sets of tripartite mullioned windows to the left, with a transept featuring a tripartite geometric window and an entrance porch projecting to the north. The porch opens eastward with a timber-sheeted door with cast-iron strap hinges and door furniture in an ashlar surround, topped by a tripartite cusped gothic leaded-and-stained glass transom.

The church is prominently sited on a large site at the junction of Church Square and Church Street, on the approach to Banbridge town centre. The grounds are lawned to three sides with a tarmacadam pathway and mature trees; a large tarmacadam car park and a large twentieth-century two-storey church hall occupy the northern boundary. The site is bounded on all sides by a low roughly coursed granite wall with coping stones topped by metal railings and granite piers. Replacement metal gates mark the main entrance at the south. A modern ramped access with stone parapet wall and metal handrail has been added to the porch at the west elevation.
