Including Quadrant Walls, St Martin And St Ninian Roman Catholic Church, George Street

St Martin and St Ninian Roman Catholic Church, designed by H S Goodhart-Rendel, was built between 1959 and 1960. This symmetrical, cruciform church features a distinctive double-bellcote on the gable and a low rubble quadrant forecourt at the street elevation (west). The church has an external altar and a Hew Lorimer crucifix at the rear (east). The exterior is harled with raised cement margins, a base course, and buttresses. It includes large triangular and pointed-segmental-arched window openings with broad timber astragals, as well as some small circular window openings.

On the street elevation (west), there is a central advanced flat-roofed porch with part-glazed timber swing doors set in a sandstone architrave. Behind this is a wide gable topped with the double-bellcote. The east elevation features a taller section on the right, where a stone, carved Hew Lorimer crucifix is mounted on the wall, complete with a slated canopy above and a timber belfry with louvred openings at the ridge. A raised platform with a stone altar is present, along with a flat-roofed sacristy to the left. The windows are predominantly small fixed types, with some metal casement windows, and the roof is covered with grey slates.

Inside, as seen in 2008, the church has white-painted walls and two flat-roofed side chapels with corner pillars. The sanctuary has a triangular roof shape, and the lady chapel is painted and stencilled in blue and gold. The lines of the corners rise to create a polygonal roof shape, with high-level lighting illuminating the sanctuary. The interior features timber pews and slatted timber doors, along with a later marble altar and lectern.

The quadrant walls at the street (west) consist of coped rubble with symmetrical gate openings.
