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

Lisarra Presbyterian Church is a Gothic church built in 1867, designed by architect W. J. Barre. The building stands on the south-east corner of the Square near Crossgar town centre.

The church is constructed in squared grey wacke rubble with sandstone dressings. A prominent four-storey tower rises to the left of the front façade, topped with a steeply pitched pyramidal slate roof incorporating a pyramidal fleche and weather vane. The roof itself is covered with geometric patterned tiles. Each face of the fourth floor has paired pointed arch window openings with timber louvers, flanked by pilasters and stone dressings. Above these windows is a slightly projecting decorative eaves course, with windows resting on a projecting cill course. The third level features a narrow slit window with sandstone in and out dressings to the centres of the south and east faces. Between the third and second levels, centred roundels appear on the south and east faces, each with drip stone merging into a string course and infilled with a blank slate panel. The first floor has narrow slit windows to the south and east faces. The ground floor contains tripartite slit windows to the south and east faces; those to the east are stepped to match the line of the internal stair. A stone string course encloses the front section at ground and first floor levels, merging with drip mouldings of the window heads.

The east gable contains paired door openings at its centre. Each opening is pointed-arched and framed by pilasters and a heavy plaster surround with archivolt. The doors and fanlights are modern and glazed. Directly above the doors is a large decorative rose window surmounted by a small trefoil. Two slit windows flank the doors to the right. Battered buttresses line both the left and right sides of the front.

The south façade is divided into six bays by equally spaced reducing buttresses. The extreme right bay comprises the south face of the tower. The remaining five bays each contain paired lancet windows with sandstone in and out dressings. The buttress at the extreme left is splayed at 45 degrees. The west gable's lower portion is obscured by a modern flat-roofed extension. The upper portion displays a large window opening of four lancet windows surmounted by a large rose window with quatrefoils, drip moulding, and sandstone in and out dressings. The north façade mirrors the south façade, except the bay at the far left is the side of the front section rather than the tower side.

The roof is covered with Bangor blue slate with three bands of Cumberland Green decorative slates. Cast iron gutters are supported on paired brackets.

To the rear of the site is a single-storey gabled hall constructed in 1932, built in dark blue engineering brick with sandstone dressings. A later single-storey flat-roofed block links the rear of the hall to its side, both additions designed to complement the main structure. The site is enclosed by a low random rubble wall.
