Trinity Parish Church, High Street, Leslie

Trinity Parish Church, built in 1860 to the design of Henry Archibald, is a box-shaped church with a Jacobean style gable and pointed towers that screen the roof pitch. It includes a spired octagonal bellcote and a "Serliana" window (a window with a central arched opening flanked by smaller, flanking arches). The church features a 3-bay aisless nave and a 3-bay Church Hall with a later extension.

The exterior is constructed of droved ashlar stone with polished surrounds, and squared and snecked whinstone with long and short work quoins for the Church Hall. Notable features include a base course, eaves course, a continuous hoodmould at ground level on the south side, hoodmoulds with decorative label stops, stone mullions, chamfered arrises and corners, and an arched cornice abutting the base of the corbelled bellcote. Panelled doors are present, along with "buckle-quoin" detailing around the oculi (round windows).

The north elevation has a round-headed doorway with a hoodmould and label stops, flanked by windows also under a continuous hoodmould. Above is a Serliana-effect window with triple-loop tracery, a hoodmould and label stops. The bellcote is polygonal, with a blind oculus and pointed arch timber louvred openings below the octagonal spire, which is topped with a ball and pointed finial. Flanking tower bays feature oculi and windows with hoodmoulds and label stops, topped by a stepped and finialled gable with a blind oculus.

The east elevation shows a 3-bay nave with round-headed windows, with a monogram in a shaped gablet breaking the eaves above one window, alongside a modern stack and flanking cast-iron downpipes. To the left is a slightly recessed, lower 4-bay hall with round-arched windows and a blinded door; a small, modern flat-roofed extension with a projecting porch is situated at the far left.

The west elevation mirrors the nave's design with round-headed windows, with the hall set back and a piend-roofed porch extension on the left including a door and window facing west. Further windows are to the south, and another extension is visible on the right.

On the south, a blinded round-headed window is visible to the left of centre, while the roof pitch of the hall is visible to the right, along with a blinded roundel in the gable. A central round-headed window is in the hall.

The church windows have diamond-pattern leaded glazing, while the hall windows have a 3-pane vertical glazing pattern, with plate glass elsewhere. The roof is covered in grey slates, with alternate fishscale slates on the spire. Other details include ashlar coped stepped skews, moulded skewputts and stacks, cast-iron downpipes and rainwater hoppers dated 1860.

The interior includes a horseshoe-shaped gallery. A wall dividing the hall has been removed, creating a "chancel" extension. Features include boarded dado with panelled doors, simple pew benches, a simply carved pulpit, altar and lectern, and further pews behind them. A 3-sided partially curved gallery is panelled with a roundel motif (containing a clock), cast-iron columns and timber brackets. The hall has an open beam roof, chevron boarded with corbelled wall posts and curved braces.

The property is surrounded by a low rendered boundary wall with railings and gates, with ball finialled painted gatepiers to the north. Coped rubble boundary walls run along the south, east, and west sides.
