St. Colman's Roman Catholic Church, Bottier Road, Kilwarlin, Moira, Craigavon, Co.Armagh, BT67 0PE

St. Colman's Roman Catholic Church stands as a grade B2 listed building on Bottier Road in Kilwarlin, Moira, County Armagh. Built in 1812, it is a free-standing, gable-fronted Roman Catholic church of T-plan form, aligned east-west and set back from the road within its own grounds on the south side of Bottier Road.

The building is constructed of pebble-dash rendered walling with smooth render plat-bands and a smooth render plinth course. It features a cruciform pitched natural slate roof with lead valleys behind lead-lined verges to all gables, surmounted by stone crosses. The eaves are finished with tooled kneeler stones and ogee moulded guttering on iron drive-through brackets with square-profile cast-iron downpipes.

The external detailing displays late Georgian Gothic character. Stepped diagonal corner buttresses with stone offsets reinforce the gables. Single pointed-arched window openings to each side elevation of both gables contain paired lancet windows set within flush chamfered sandstone frames, glazed with iron quarry work featuring cylinder glass and quatrefoils above. Pointed-arched door openings with chamfered rendered surrounds contain paired replacement hardwood panelled doors with overdoor panels.

The north gable displays a single door opening and a diamond-shaped marble date plaque with hood moulding and curtail stops. The inscription reads: "DEO, OPT. MAX., UNI ET TRINO., SUB INVOCATIONE, SANTI COLMANI., MDCCCXII" (1812). The west entrance gable has a door opening with a sexfoil stone panel above.

The east gable, containing the altar, is plain ruled-and-lined and abutted by a single-storey gabled vestry with rendered chimneystack to the gable and smaller pointed-arched window openings detailed as those of the main structure. The vestry has a pointed-arched door opening to the north with diagonally-sheeted hardwood door and over panel, and a square-headed door opening to the south with replacement hardwood panelled door. A lean-to toilet block was added adjacent to the vestry around 1990.

The building is surrounded by cemetery grounds with upstanding marble and stone grave-markers dating from the late eighteenth century to the present. A low rendered wall with iron railing encloses the site to the road. A presbytery was constructed to the west around 1960. A concrete paved ramp leads to the north entrance opening onto a bituminous path encircling the entire church, connecting to a pair of short driveways to iron entrance gates on Bottier Road.

Historical records from the Townland Valuations of 1828-40 confirm the chapel with an outshot vestry, which corresponds to the building's footprint shown on the first edition Ordnance Survey map of 1833. This arrangement remained unchanged on subsequent editions of 1858, 1903, and 1916. The building underwent extensive restoration in 1967, which resulted in the complete loss of internal historic fabric. The roughcast render with banding applied at that time altered the external character of the building, though a portion of the original render can still be observed over the vestry on the east projection.

The church remains significant as a relatively rare early nineteenth-century pre-emancipation Roman Catholic church with a T-plan layout and retains its simple external Gothic appearance with stone lancet windows and angled buttresses. Despite the substantial internal alterations of the 1960s which detract from its late Georgian character, it continues to hold social and cultural importance for the local community.
