St Ignatius R.C. Church, Young Street, Wishaw

St Ignatius Roman Catholic Church, built in 1865 by George Goldie, with a south aisle added in 1906 by Bruce and Hay, is a Gothic-style basilica aligned east-west. The church is constructed of squared and tooled yellow sandstone with ashlar margins, featuring projecting eaves and coped parapet gables. Hoodmoulds are present above the principal openings.

The west (principal) elevation has four bays and a buttressed gable. It features lancet windows on the ground level, and a large three-light pointed arch with geometric tracery in the gablehead. A set-back gabled porch is positioned on the right, containing a pointed entrance arch with a rolled moulding supported by engaged columns. A quatrefoil is set within a square moulded panel above the square-headed door, and two narrow vertical vents are at the apex, topped by a cross finial. An oversize crocketed buttress sits on the right.

The east (rear) elevation is semicircular, forming a chancel, with a dividing band. A gabled, cusped projecting niche is centrally located on the upper section, flanked by three lancets on each side. Returns to the aisles feature large oculi with an unusual cusped star in the centre.

The south (side) elevation showcases a belltower centrally located to the left, a blank return of the porch to the left, and a six-bay aisle to the right, alternating advanced gabled chapels with paired lancets. Each porch has paired lancets, with a quatrefoil to the cross gable and a cross finial, except for the chapel adjacent to the tower.

The belltower is a three-stage symmetrical structure. A large lancet arch, originally the main entrance, is roll-moulded and supported on short engaged columns. The outer gable entrance is now filled with paired lancets and multifoil detailing. A porch abuts the tower on the left, and the aisle extends to the right. A dividing band marks the second stage, at the height of the nave eaves, with a narrow recessed blind arcade. A further dividing band separates the third stage, incorporating a two-light pointed arch opening with timber louvres, roll moulding, raised quoins, engaged columns, stone brackets and a dog-tooth cornice. Projecting stone gabled lucarnes are present on the spire, alternating between plain ashlar and carved fishscales, culminating in a finial.

The north (side) elevation has paired lancets in most bays, with an advanced gabled porch at the centre. An advanced wing, formerly a boilerhouse, is positioned on the far right, featuring buttresses, an inset panel to the gable end, and a battered wallhead chimney to the return.

The church features diamond leaded glass, with lilies pattern stained glass in the north chapel and modern stained glass at the east end. Coped skews have gabled kneelers. The roof is covered with graded grey slates and has decorative wrought-iron cresting at the east end, lead flashing, and decorative earthenware cresting on the south aisle and boilerhouse roofs. Moulded cast-iron rainwater goods with square hoppers are also present.

Inside, the church has a four-bay nave with pointed arch arcading to the aisles, supported by columns with stiff leaf capitals. A wooden gallery occupies the west end bay and a wooden panelled screen is at the west end. Mosaic flooring with a cross motif is featured at the base of the tower.

A coped wall of squared sandstone runs along the east, south, and west boundaries. A single octagonal gatepier stands at the west, featuring a blind cusped arcade on the upper stage, a cornice, a pyramidal cap, a wrought-iron finial, and a wrought-iron gate.
