Congregational Church, 101-103 Donegal Street, Belfast, County Antrim, BT1 2FJ

Donegall Street Congregational Church is a symmetrical, largely free-standing church built in the Gothic Revival style, progressively constructed and remodelled in stages between 1860 and 1955 to the designs of several architects. The main body of the building is T-shaped in plan, with additional three-storey wings flanking each side of the principal west-facing façade. Nothing visible survives of the original church built around 1860 by William Raffles Brown, owing to the extent of later reconstruction.

The building's history is a complex one. The Congregational community in Belfast traces its origins to a late 18th-century revival movement which reached the north of Ireland in 1801, when Scottish Independent church leader James Haldane preached in the locality. The first church on this site was designed by James Harper and is shown on the first edition Ordnance Survey map of 1832–33 as a plain rectangular structure set back from the street behind an iron palisade. It was built using a loan of £500 from Robert Haldane, a clergyman and brother of James. Significantly, this site is where the Congregational Union of Ireland was formally established on 25th and 26th November 1829, making it a pivotal location in the history of the Congregational church in Ireland.

In March 1859, as the Ulster Revival was gathering momentum, the foundation stone of a new church was laid to designs by William Raffles Brown, an ecclesiastical architect also responsible for churches in Londonderry and Galway. Raffles Brown's church was in the early decorated Gothic style and comprised a nave of five bays seating 560, with schoolrooms and lecture rooms in the basement. A full description published in the Dublin Builder on 1st April 1859 suggests that subsequent rebuilding deliberately reproduced some of Raffles Brown's detailing, particularly in the roof timbers. Raffles Brown's original proposal had included two flanking buildings either side of the church, with shops at ground floor and classrooms above filling the Donegall Street frontage. These were not built until 1871, when a new architect, Luke Livingston Macassey, was engaged for the work. A double stair was added in front of the church at this time, and a gallery was also installed around three sides of the nave. The church was listed in Griffith's Valuation (1856–64) at £200. Extensive renovations and improvements were carried out around 1898 to designs by Thomas H. McCaul, by contractors McLaughlin and Harvey.

The church was destroyed by fire in 1931 and then severely damaged during the Belfast Blitz in 1944. Reconstruction in 1932–34 was carried out to designs by John Seeds. This work replaced the original Scrabo stone frontage with Portland stone and brought the front elevation forward so that it now sits level with the flanking wings. The contractor was McQuoid and the cost was £15,000. Repairs following the Blitz damage were carried out in 1955 to designs by Samuel Stevenson and Sons; the upper portion of the front elevation, including the rose window, dates from this phase. A photograph of around 1900 confirms that the flanking wings are the originals of 1871, though they have since been altered at ground floor level and along the roofline, which was formerly double-gabled.

The building as it stands is an amalgamation of late 19th-century and early-to-mid 20th-century interpretations of ecclesiastical Gothic architecture, with much historic fabric surviving to reflect this varied history.

Externally, the roof is of pitched construction in slate, concealed behind a parapeted gable on the principal elevation, which is surmounted by stepped proportions and a projecting decorative centrepiece. Half-round cast-iron and uPVC rainwater goods are mounted on a projecting eaves course. The walling throughout the main body is uncoursed, square-cut ashlar sandstone over a double projecting base, with dressings to the central section in limestone. Unless noted otherwise, openings are Tudor-arched with leaded windows and perpendicular-style tracery; ground floor openings have cusped heads. Doors throughout are replacement panelled timber unless otherwise stated.

The principal west elevation is dominated by a large stained-glass concentric rose window dating from around 1952, set to the centre of the upper storey and surmounted by a hood label terminating in foliated and stepped ends. The side windows of the central section are vertically divided by pairs of mullions, with decorative panels providing horizontal division. The corners of the central section are chamfered and have stepped limestone quoins. A moulded string course separates the ground and upper floors, and advancing piers to the outer edges rise to points with cusped panelled inserts. A stone panel above the central doorcase is inscribed "DONEGALL STREET CONGREGATIONAL CHURCH" and is flanked by twin-pane, cusp-headed windows with a continuous moulded cill course. The doorcase itself is a centralised Tudor-arched opening framed by outer pilasters extending up to the string course, with spandrels containing blind tracery. Within the arch are nine cusped-headed lancet windows in the upper section, set over a pair of double-leaf doors with Tudor-arched heads and decorative quatrefoils to the spandrels.

The three-storey gable-fronted side wings to north and south are symmetrical and executed in similar style and materials, likely dating from the late 19th century. Each wing is two openings wide. They have pitched slate roofs with gables breaking through the eaves and half-round cast-iron rainwater goods with some decorative hoppers mounted on a projecting eaves course. The walling is similar to the main façade but in a darker yellow stone. Windows are paired leaded lancets with pointed-arch mouldings enclosing quatrefoils, and windows and doors are flanked by foliated columns or pilasters carrying a continuous cornice. Each upper floor has two window openings; the ground floor has two pointed-arched openings with squared doors and blind tracery to the moulded heads above.

The north elevation, along with all remaining elevations, is smooth rendered and painted. It has two large windows to the upper floor right of centre, set in stepped stone architraves and separated by an offset full-height buttress, with a similar pair of windows to the left of centre comprising the upper portion only. Two smaller corresponding windows below on the right side are uPVC inserts with square heads, reconstituted stone sills, and plain architraves. Left of centre on the main elevation, a two-storey flat-roofed block forming the north transept contains two pointed-arched windows similar in style but smaller than those on the main elevation, over tripartite plain glass squared windows below. The ground floor of this transept is abutted by a mono-pitched extension with rendered walls and a corrugated plastic roof. The right cheek of this block contains a small flat-roofed porch with replacement multi-panelled square-headed doors to both floors, each with a plain glass pointed-arched transom above; the left cheek is abutted by a rear extension. To the far right of the north elevation, a side wing contains two pairs of staggered, vertically aligned windows above a pointed-arched passageway; the upper windows are pairs of squared metal casements with a common projecting cill, while the left-side windows are pairs of cusped lancets framed by flat-arched stone architraves with a hood mould over.

The east (rear) elevation is largely obstructed by neighbouring buildings. The main elevation is blank and is abutted by a lower pitched chancel with uPVC squared window openings at each level, metal-framed at ground floor. The right side of the rear is abutted by a two-storey flat-roofed block extending northward with uPVC windows to left and right cheeks; the ground floor of the left cheek abuts a neighbouring building, with mono-pitched metal-framed glazing spanning the gap.

The south elevation is generally detailed as the north, though the ground floor block to the right side contains a pair of uPVC windows at ground floor level, with a similar window to the right cheek and a single door opening to the left cheek.

The building directly addresses the Donegall Street frontage, located on the eastern side of the street in the busy urban environment of Belfast city centre. The compact site is surrounded by multi-storey modern office buildings which generally enclose the area, though a single-storey painted masonry wall stands to the south-east. The outer doors on the main façade lead through rendered passageways into the north and south yards. A concrete and metal dog-leg escape stair leads from the north yard to the first floor doorway in the north elevation. The north and south side wings create the appearance of a terrace along Donegall Street; the Irish News Building is located a short distance to the north. The building lies within a conservation area.

The Congregational community in Belfast has declined in numbers in recent years and the church building has been leased to Redeemer Central, a recently established evangelical church based in Belfast.
