St Mary's R.C. Church, St Vincent Place, Lanark

St Mary's Roman Catholic Church, located on St Vincent Place, Lanark, was originally built between 1856 and 1859 by George Goldie and Matthew Hadfield. It suffered a fire in 1907 and was rebuilt between 1908 and 1910 by Ashlin and Coleman. The church is constructed of snecked and stugged pink sandstone with yellow ashlar dressings, and is designed in the Gothic Revival style, inspired by the late 13th century.

The building comprises a chancel, flanking side chapels, transepts, a nave, aisles, and a former baptistry located at the southwest. A tower and spire are attached to the north aisle at the west.

The exterior features a 6-bay buttressed nave, a wheel window above a blank arcading at the west front, and a mural stair within a projecting half-octagon. A projecting 5-sided baptistry is present at the southwest corner. The aisle windows have geometric tracery, while the clerestory windows feature plate tracery set within shallow squared recesses. The transepts incorporate two windows in both the north and south gable ends, relating to the original church design. A rose window is positioned above the transepts. The chancel is divided by piers and includes three cusped lancet windows each, complete with hood moulds. A boldly detailed corbel table runs along the chancel. The east end displays three buttresses, a blind arcade below the central rose window, and flanked pointed niches with crocketted gables and pinnacles. A tall, three-stage buttressed tower and spire rises prominently. A porch at the base of the tower features two arched entrances with nook shafts, niches containing figures, and crocketted canopies. Narrow lancet windows are incorporated in the second stage of the tower, and tall, louvred lancets illuminate the bellfry. A pierced parapet tops the tower, punctuated by pairs of octagonal, crocketted angle pinnacles; the inner ones clasping the stone-faceted spire. The spire is decorated with bands of trefoil ornamentation and crocketed points, topped by a weathervane.

The roof is covered in fishscale slate with tiled ridges and carved crosses adorn the gable heads.

Inside, an organ loft at the west is supported by clustered piers and three segmental arches. The nave arcade is defined by polished Galway granite columns with elaborately carved foliate capitals. Niches containing figures are set within the spandrels, supported on corbelled squat columns, with attached shafts and capitals supporting the wooden roof trusses. The nave roof is timber-panelled with painted borders. The chancel features decorated arcades to the north and south, leading to the side chapels. Triple lights are set in the clerestory. A marble altar by Goldie is present, complemented by a reredos of 1901 by Pugin and Pugin, crafted from marble and Caen stone. The rose window is positioned beneath a pointed arch with carved spandrels, and the ceiling is finished with a plastered rib vault. An altar in the Lady Chapel, designed by Pugin and Pugin in 1895, is also present.
