Old Parish Church, Main Street, Wishaw

The Old Parish Church on Main Street in Wishaw is possibly designed by Thomas Burns and dates from 1840, with additions made in 1874, 1891, and 1931. This plain Venetian Gothic church has a rectangular plan oriented northeast to southwest, featuring a three-stage entrance tower at its center topped with a stone spire. The building is constructed of yellow and pink ashlar sandstone and includes hoodmoulded semicircular openings, chamfered reveals, and windows with bipartite Venetian tracery. Notable architectural elements include a battered base course, a continuous cill course, and a projecting cornice at the eaves.

The southwest elevation, which is the principal facade, is symmetrical with three bays. The entrance tower is advanced and features an engaged clock tower. The central door has a fanlight above it, with rolled moulding around the reveal. Below the window, there is a string course cornice, and the top stage of the tower has a semicircular arch with an arcaded design, ending in a Lombard frieze and a projecting cornice. The tower is adorned with cast-iron brattishing at the blocking course and stone obelisk finials at the corners framing the spire, which is topped with a cross finial. The clock faces are housed in projecting pedimented and corbelled timber cases. The flanking bays have shouldered wallheads, with their windows positioned slightly lower than the central window, and the wallplane is recessed.

The northeast elevation features a 19th-century addition that is obscured by modern structures. The southeast elevation is symmetrical with five bays, regular fenestration, rectangular windows at the ground level, a door in the far left bay, and semicircular arches for the upper storey windows. The northwest elevation mirrors the southeast.

The church features leaded glass windows, a roof covered with grey slates and lead ridges, and cast-iron rainwater goods.

Inside, there are flanking stairs leading to a gallery on either side. The center of the nave has stained glass depicting the Tree of Life, with flanking doors that also have fanlights. The galleried nave leads to a full-height semicircular arch that opens into the chancel, which was added in 1874. The rear wall of the chancel features two large stained glass windows depicting saints, dedicated in memory of Lord and Lady Hamilton. The chancel also has timber panelling and a fitted organ to the right. There are flanking vestry and session house areas.
