St Colmac's Church, Bute

St Colmac's Church, located in Bute, was likely designed by Paterson of Largs and is dated 1835. It is a symmetrical, two-stage, three-by-three-bay church built in a plain Gothic style, featuring a three-stage square-plan belfry tower at the center of the east gable. The church is constructed from harl-pointed rubble sandstone with pink sandstone dressings and a coursed sandstone ashlar tower. It has a raised base course, a moulded string course on the tower, corniced eaves, and a polished blocking course. The building includes narrow strip quoins, droved pink rubble sandstone quoins, and droved pink rubble long and short surrounds to polished, pointed-arched openings, with chamfered reveals, chamfered cills, sandstone mullions, and architraved hoodmoulds.

The east elevation features an advanced tower at the center, which includes a two-leaf timber panelled door at the ground level, a timber panelled fanlight set in a pointed-arch surround, and a large Y-traceried window above. Gableted pinnacles rise above the second stage cornice on both the left and right sides, with a small louvred opening in the upper stage. There are single recessed windows flanking the entrance at ground level.

Both the north and south side elevations have Y-traceried windows in all three bays. The west rear elevation has a large Y-traceried window centered beneath the apex, with carved figurative stops to the hoodmould. Above this window is a small blind opening dated "1835," topped with a crucifix finial. The ground level features boarded, Tudor-arched openings in the bays flanking the center.

The church has predominantly opaque glazing, with some parts missing, and retains an original stained glass window on the west side. The roof is missing, and there are replacement rainwater goods.

The interior was not seen in 1996. Surrounding the church is a graveyard with various headstones. The site is enclosed by a random rubble wall with rubble coping. At the entrance, there are stop-chamfered, square-plan ashlar piers with moulded cornices and pyramidal caps, along with wrought-iron vehicular access gates.
