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

Trinity Presbyterian Church, located at the junction of Main Street and Newtownards Road in Greyabbey, is a two-storey gabled Presbyterian church built in 1903 to designs by T. Pentland. The building displays Arts and Crafts influences and is constructed in rockfaced snecked rubble with red sandstone dressings to openings. The roof of the main church and rear section is laid with Bangor blue slate, except where modern PVC guttering has been added to the north-east elevation, which retains cast iron rainwater goods. The boundary features decorated cast iron railings with gates and a low rubble wall to the south-east and south-west elevations.

The front south-west elevation is asymmetrical, dominated by the gable end of the main church body with a squat square buttressed corner tower at the south-east and a small single-storey buttressed projection at the north-west corner. The gable centre contains a large elliptical arch doorway with red sandstone dressings. The door itself is timber panelled with an elliptical arch head, four-pane fanlight and sidelights, the latter two features incorporating leaded lights. Stone steps lead up to the entrance. Directly above at first floor is a large three-light window with semicircular arch head and Y-tracery mullions forming three gothic arch-headed lights, accompanied by sandstone dressings and a gothic arch drip stone moulding. A moulded first-floor course runs across the elevation. At the gable apex sits a small semicircular headed niche with matching drip stone moulding.

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

The single-storey buttressed projection at the north-west corner features a window matching the ground floor of the main tower and 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 and contain windows similar to those on the ground floor of the tower, but larger. On the north-west side, the second window from the left lacks a three-light timber frame and is instead filled with stained glass. The second window from the right on the south-east side is similarly treated. Both sides have a sandstone cill course.

The rear north-east section is a two-storey gabled structure containing rooms for the minister and other purposes, sitting at right angles to the main church body. The south-east gable of this section features a large buttress on its left side and a first-floor window matching the tower's ground floor type. At ground floor level, a plain sheeted timber door stands to the left, with two square timber windows having 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 church, 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 section where it meets the main church body.

The north-east elevation of the rear section is rendered and features two modern windows at ground floor level in the centre and three modern windows with semicircular arch heads at first floor. A large modern church hall is attached to the right side of this elevation.
