Belmont Presbyterian Church, 92 Sydenham Avenue, Belfast, County Antrim, BT4 2DT

Belmont Presbyterian Church is a double-height red brick Gothic Revival church built in 1860–61, located on Sydenham Avenue in the Strandtown area of east Belfast. It is an exceptional example of its type, notable for being the combined work of several of Belfast's most distinguished 19th-century architects, and for retaining its interior layout largely unchanged since alterations and additions carried out around 1900. The listing covers the church and its gate screen, and the building has group value alongside the adjacent listed church hall and gate lodge.

The church is built to a cruciform plan set on an east–west axis, with a single-storey flat-roofed porch and a square-plan four-stage tower to the west. A modern L-shaped extension and hall abuts the north and east sides. The roof is pitched natural slate with decorative cut slate bands, crested red clay ridge tiles, red clay finials, and sandstone coping to the gables. Cast-iron ogee-moulded guttering with circular downpipes is carried on chamfered yellow brick corbels at eaves level. The walls are red brick laid in English garden-wall bond with buff brick dressings, quoins, and a chamfered plinth course. Windows throughout are lancet form with sandstone keystones and splayed sills, fitted with stained leaded glazing and fixed external secondary glazing unless otherwise noted.

The principal west elevation presents gables at the ends of both the nave and north aisle. A projecting single-storey four-bay porch runs across the front, with a three-sided outshot with a hipped slate roof connecting its northwest side to the north aisle gable. The tower stands at the southwest corner and rises in four stages with pinnacles, a parapet, and three-stage angled buttresses. At belfry level each face has a large trefoil louvred opening; the second stage has a lancet window; the first stage has a door opening to the south elevation and two small trefoil windows to the west. The main nave gable carries a large five-part traceried window and a carved cruciform to the apex; the north aisle gable has a lancet window. Both gables have raised stone verges and small lancet openings at higher level. The porch has two-stage buttresses and a parapet, with two square-headed door openings to the west and one to the south, each with segmental arch hood mouldings and decorated tympana, and modern glazed timber doors opening onto a platform with three nosed stone steps. Square-headed stained leaded glass windows are set into the north and south bays of the porch and into the outshot.

The north elevation comprises the north aisle and north transept. The north aisle is five bays wide, each bay separated by a three-stage buttress, with double lancet window openings to each bay. The north transept projects as a gabled five-sided canted bay with two-stage buttresses. Its north face has a large three-part tracery window with pointed-arch hood mouldings on head stops, and a lancet window to each canted bay. The east elevation is largely obscured by the adjoining modern hall, which dates from the 1960s and is of little architectural interest. The south elevation consists of the south aisle, the tower at the west end, and the south transept at the east end. The south aisle is four bays wide, each bay separated by a two-stage buttress with double lancet windows. The south transept is a gabled five-sided canted bay with three-stage buttresses. Its south face has a large three-part tracery window with pointed-arch hood mouldings on head stops, and a lancet window to each canted bay.

Internally, the nave and aisles are covered by a handsome exposed timber ceiling, and the building contains good-quality stained glass windows. The interior layout has remained largely unchanged since the alterations and additions of around 1900.

The church sits within its own grounds, with the modern hall and extension to the north and east. The site fronts onto Sydenham Avenue. The grounds are partly lawned and partly concrete paved, and are enclosed to the south by a red brick wall with stone coping topped by cast-iron railings. Square red brick gate piers with buff brick quoins and single-stage buttresses, topped by cast-iron finials, support cast-iron gates at the main entrance. A cast-iron gate and hedge mark the southwest pedestrian entrance. The listed church hall and gate lodge lie to the southeast, with car parks to the west and north.

The congregation of Belmont Presbyterian was formed from local missions organised by Ballymacarrett, and the land for the present building was donated by Sir Thomas McClure of Belmont House, who also personally financed its construction. The original church was designed by William J. Barre (c.1826–1867), a Newry-based architect who had just moved to Belfast following his success in the competition to design the Ulster Hall in 1860. The design of Belmont Presbyterian Church was the first contract Barre undertook after relocating to Belfast, and was itself the result of an architectural competition in which Barre was the sole entrant. Construction was carried out by the local firm of Edward Armstrong, and the church — together with a sexton's house (now listed separately) and a schoolhouse (since demolished) — was completed in 1861 and opened for worship on 26th January 1862. The combined rateable value of the church and its associated buildings was assessed at £120 in the Annual Revisions.

As architectural historian C. E. B. Brett has noted, Belmont Presbyterian Church has been so often enlarged over the years that almost nothing of Barre's original building is still visible, yet the successive additions carried out between 1873 and 1898 have given the building what Brett describes as a very pleasing air of mellowness and antiquity. The first major addition came in 1873, when Anthony Thomas Jackson (1838–1917) added the current south aisle and transept. In 1887 the north aisle and presumably the north transept were added by Young & Mackenzie — a firm described by the Dictionary of Irish Architects as the leading architects for the Presbyterian Church in the north-east of Ireland. By this point the sexton's house and schoolhouse were being valued separately, and the church's individual rateable value had been reduced to £95. The most significant transformation came in 1898, when Vincent Craig (1869–1925) added the present square tower and extended the nave. Craig had been articled to the architect W. H. Lynn between 1885 and 1889, established an independent practice in 1891, and is recognised as the leading proponent of the aesthetic Art Nouveau movement in Ireland. He was the younger brother of James Craig (Viscount Craigavon), the first Prime Minister of Northern Ireland, who was a lifelong member of Belmont Presbyterian: baptised in the church, and with his funeral held there in 1940 before his burial at Stormont. Brett describes the tower Craig added as very un-Presbyterian in character. Craig had also designed Belmont Primary School in 1889–92. Following the reconstruction of the building, its rateable value was raised to £250 by 1910.

In 1931 the church was refurbished and reopened by James Craig. The adjoining church hall was also constructed at this time, both works carried out to designs by the Belfast-based architect James Corden Stevenson, who was active from the 1920s to the 1950s and had previously designed Cregagh Presbyterian Church and its hall in 1929. The rateable value of the church and hall was increased to £520 under the First Revaluation of 1935. A second church hall was added to the east side in the 1960s, and by the end of the Second Revaluation (1956–72) the combined value had risen to £1,684. The church was listed in 1986, the same year in which a restoration of the exterior brickwork was carried out. In 2001 a modern single-storey connecting corridor and extension was installed to link the church to the 1931 hall. The church remains in active use as a place of worship.
