St Mary's R.C. Church, 167 George St, Paisley

St Mary's Roman Catholic Church, located at 167 George Street in Paisley, was designed by the architects Pugin and Pugin in 1891 and showcases a Geometrical Decorated Gothic style. The church features a rectangular plan with a seven-bay nave, buttressed aisles, and a projecting porch. An apse was added in 1905. The exterior is constructed of squared rubble with ashlar dressings. The front of the church has a gabled end with a five-light traceried window and a semi-vesica shape in the gable. There are angle buttresses and a three-light traceried window at the west end of the north aisle. To the south, there is a finialled gabled porch that is set forward, featuring two entrance arches and a canopied niche above a statue. The sides of the porch have three cusped lights under a segmental-headed window, with similar windows in the aisles and clerestory. Three confessionals were added to the west aisle, leading to the apse, which has a rectangular ground level and a semi-octagonal ventilator topped with a spirelet.

Inside, the church has an arcade supported by octagonal piers. There is an organ gallery at the west end with a fretted balcony. The altar rails and altarpieces in the apse and flanking chapels are elaborately carved in stone and marble. Four niched statues flank the apse windows, and both the apse and nave feature a couple roof with painted square panels. The church also includes modern stained glass windows.
