Trinity Presbyterian Church, Main Street, Greyabbey, Newtownards, Co. Down, BT22 2NE

Trinity Presbyterian Church is a two-storey gabled Presbyterian church of 1903, designed by T. Pentland, possibly influenced by Arts & Crafts principles. It stands at the junction of Main Street and Newtownards Road in Greyabbey. The building is constructed in rockfaced snecked rubble with red sandstone dressings to openings, and features a squat square corner tower. The roof of the main church and rear section is slated in Bangor blue. Cast iron rainwater goods with PVC guttering serve the north-east elevation. Decorated cast iron railings with gates and a low rubble wall enclose the south-east and south-west frontages.

The front south-west elevation is asymmetrical, consisting of the gable end of the main body with a tower at the south-east corner and a small projection at the north-west corner. At the centre of the gable is a large elliptical arch doorway with red sandstone dressings. Above the doorway sits a four-light mullioned window. Within the elliptical arch is a timber-panelled double door with elliptical arch head, four-pane fanlight and sidelights featuring leaded lights. Stone steps lead to the door. At first-floor level, directly above the doorway, is a large three-light semicircular-headed stained glass window with Y-tracery mullions forming three Gothic arch-headed lights. The window has sandstone dressings and a Gothic arch drip stone moulding. A moulded first-floor course runs across the elevation. At the gable apex is a small semicircular-headed niche with similar drip stone moulding.

The squat buttressed two-storey square tower at the south-east corner projects slightly forward from the gable. At ground floor level it contains a semicircular-headed three-light timber window with modern coloured glass, sandstone dressings and drip moulding. A moulded course sits above this window. At first-floor level are two paired windows of similar design, with a sandstone apron panel inscribed "This stone was laid by Mrs. Montgomery, Rosemount 6th August 1903". Above these windows runs a frieze consisting of a series of recessed arched niches, which continues around the south-east and north-east faces of the tower, which are otherwise blank. The tower is capped with a Bangor blue slated hipped roof.

At the north-west corner of the front elevation is a single-storey buttressed projection with a ground-floor window matching that of the tower. This projection also has a slated hipped roof with slight overhang and exposed rafter ends. A buttress with pinnacle rises between this projection and the main front gable.

Both the north-west and south-east sides of the church are buttressed with windows matching the ground floor of the tower, but larger in scale. The second window from the left on the north-west side and the second from the right on the south-east side differ, being filled with stained glass rather than timber-framed lights. A sandstone cill course runs along both sides.

The rear north-east section is a two-storey gabled addition containing ministerial rooms, positioned at a right angle to the main body. The south-east gable of this rear section features a large buttress to its left and a first-floor window matching the tower ground-floor design. At ground-floor level are a plain sheeted timber door and two square timber windows with coloured leaded lights to the right. The north-west gable of the rear section projects beyond the north-west side of the main body and contains a large first-floor window similar to that on the front gable of the main body, but with timber frame and coloured glass. At ground-floor level are three square-headed window openings with sandstone dressings and coloured leaded lights. A plain sheeted timber door is set in the south-west side of this rear section.

The north-east elevation of the rear section is rendered and has two modern windows at ground-floor level in the centre, with three modern semicircular-arch-headed windows at first-floor level. A large modern church hall is attached to the right-hand side of this elevation and was constructed after approximately 1975.
