Lisarra Presbyterian Church, The Square, Crossgar, County Down, BT30 9EE

Lisarra Presbyterian Church is a Gothic church erected in 1867 to designs by W. J. Barre, located on the south-east corner of the Square in Crossgar. It replaced an earlier church dating to around 1770 that had stood in Lissara townland to the north, and retains the name of its predecessor.

The church is constructed of squared greywacke rubble with sandstone dressings and features a distinctive four-storey tower to the left of the front façade, crowned with a steeply pitched pyramidal slate roof, a pyramidal fleche, and a weather vane. The main roof is covered in Bangor blue slate with three bands of Cumberland Green decorative slates.

The tower rises from ground level with tripartite slit windows on the ground floor to its south and east faces, with those to the east side stepped to match the internal stair line. The first floor contains narrow slit windows with in-and-out sandstone dressings to the south and east faces. The second level is marked by a centred roundel on each of the south and east faces, featuring drip stone merged with a string course and blank slate infill panels without inscription. The third floor repeats narrow slit windows, while the fourth floor carries paired pointed arch window openings with timber louvers, pilasters, and stone dressings on each face. A slightly projecting decorative eaves course surmounts these windows, which rest on a projecting cill course.

The east-facing gable of the front section contains a pair of pointed arch door openings at ground level, each framed by pilasters and a heavy plaster surround with archivolt. The doors and fanlights are modern glazed insertions. Directly above these doors is a large decorative rose window surmounted by a small trefoil, flanked by two slit windows. Stone string courses enclose the front section at ground and first floors, merged with drip mouldings of the window heads. Battered buttresses flank the front façade to both left and right.

The south façade is divided into six bays by equally spaced reducing buttresses. The easternmost bay comprises the south face of the tower, whilst the five remaining equal bays each contain paired lancet windows with sandstone in-and-out dressings. The buttress to the extreme left is splayed at forty-five degrees. The north façade mirrors the south elevation, except that the bay to the far left is the side of the front section rather than the tower side.

The lower portion of the west gable is obscured by a modern flat-roofed extension. The upper portion features a large window opening comprising four lancet windows surmounted by a substantial rose window with quatrefoils, drip moulding, and in-and-out sandstone dressings. Cast iron gutters throughout are supported on paired brackets.

An organ was installed within the church in 1920. In 1932, a single-storey gabled hall was constructed to the rear in dark blue engineering brick with sandstone dressings. A linking block was added in 1979, connecting the hall to the side of the church, both designed to complement the main structure. The interior of the church underwent complete renovation in 1984, at which time mock stone decoration was applied to the walls. The site is enclosed by a low random rubble wall.
