St Columba's Parish Church, Gallowgate Street, Largs

St Columba's Parish Church, located on Gallowgate Street in Largs, was designed by architects Henry Steele and Andrew Balfour and built between 1891 and 1893. This church features a cruciform plan in the first pointed Gothic style, with a hall to the east and a tall three-stage square tower with a spire at the northwest corner. The exterior is constructed of red snecked and stugged ashlar stone with polished dressings.

The tower is notable for its tall set-back buttresses on the first and second stages, and it has a pointed-headed hood-moulded door on the north elevation. The second stage is tall and features lancet windows high on each face, flanking a gabled central pilaster strip. The third stage includes engaged, banded octagonal angle piers topped with pinnacles, tall pointed-headed louvered belfry openings, and a clock on each face at the base of the spire, which is faceted.

The main entrance is located in the west gable, flanked by pinnacled angle buttresses. It features a central gabled doorway with nook shafts under a moulded pointed arch and hood-mould, with flanking buttresses. Above this entrance are tall triple plate-traceried lights with shafted jambs and moulded arches, and a vesica in the gable head. The church has a five-bay buttressed nave and aisles, with paired lancets featuring shafted jambs and hood-moulds leading to plate-traceried clerestory windows.

At the east end of the aisles is a squat two-stage octagonal tower with a faceted roof, each side having a pointed-headed door. The large transept windows are pointed-headed with geometric tracery above a blind arcade, flanked by gableted and pinnacled angle buttresses. A small decorative fleche is also present. The five-bay hall to the east is oriented north-south and features five paired lancets in the clerestory and aisle. A gabled porch in the north gable, below triple lancets, is approached from the west by steps with a pierced balustrade and square low terminal piers, along with a small fleche. The church has slate roofs throughout.

Inside, the nave features a clustered columned aisle arcade. The west and transept galleries have panelled balcony fronts. The organ was made by Willis of London. The south transept window was created by Stephen Adam in 1892, the north transept window by Winfields in 1891, and the west window by Cottier and Son of London in 1891. Some later aisle windows were designed by Gordon Webster.
