St Patrick's Roman Catholic Church, Strathleven Place, Dumbarton

St Patrick's Roman Catholic Church, located on Strathleven Place in Dumbarton, was designed by the architects Dunn and Hansom of Newcastle and built between 1900 and 1903. This Gothic church features eight bays and an aisled layout, with a lower chancel and sanctuary that were added later. A detached three-stage tower was added to the west between 1926 and 1927, designed by Pugin and Pugin of London. The church is constructed of bullfaced red snecked rubble with polished dressings.

The principal gabled elevation facing Strathleven Place is simply detailed, featuring two doors recessed under moulded arches, flanked by blind arches. Above these is a cross-finialed gable with a figure of St Patrick in a canopied niche, along with three lancet windows and angle buttresses. All openings have hood-moulds, and there is a gable oculus. The aisle windows are single, hood-moulded, and plate-traceried, while paired, hood-moulded windows with cusped heads are found in the aisles and clerestory. The west aisle includes a gabled door at the north end, and there is a traceried window in the south gable of the chancel. The sacristy at the southwest corner has a flat roof, while the other roofs are slated with red ridge tiles.

Inside, the church features aisle arcades supported by circular piers. There is a small organ gallery at the north with a panelled front and flanking pipes, and a baptistry located in the eastern aisle. The high altar, along with its reredos, is made of marble and is set beneath a Gothic baldacchino. Marble altars and reredos are also present in the chapels at the south end of each aisle, and there is an octagonal marble pulpit. The walls are adorned with painted panels depicting the Stations of the Cross, and a rood hangs from the chancel arch. A painted figure of St Michael by Eric Gill can be found within, alongside some leaded glass windows and a timbered roof.

The tower is connected to the west aisle and features traceried windows on two faces of its lower stage. The second stage has a figure in a canopied niche on three faces, flanked by cusped lights. Each face of the third stage has a large pointed, louvered, and traceried belfry window. The tower is supported by stepped angle buttresses, which enclose a stair at the northwest and rise into pinnacles, linked by a corbelled parapet that is pierced and crenellated.

The church is set behind a low boundary wall made of red bullfaced rubble, which includes square gatepiers and simple iron gates and railings.
