Churchyard, St Andrew's Parish Church, Main Street, Alexandria

The Smollett Mausoleum, located in the churchyard of St Andrew's Parish Church on Main Street in Alexandria, dates back to 1840. This Gothic hall church features a rectangular plan and is constructed from painted stugged squared and snecked sandstone, with ashlar margins and dressings, and rough render on the side and rear elevations. The building includes a base course, an eaves cornice, and strip quoins.

On the west elevation, there is a two-stage tower with a spire situated in the center of a buttressed bay. It has a round-arched door with scalloped colonnette moulding and a two-leaf panelled door. Above this door is a three-light round-arched window, with corbelled clocks on each side and gabled sawtooth louvred lucarnes. The octagonal narrow spire is topped with a finial and a lead weathervane, and there are gabletted, pinnacled pilaster buttresses. The flanking buttressed bays feature round-arched windows with scalloped hoodmoulds.

The north and south elevations display an ashlar pilaster that divides the nave from the tower, with a five-bay nave and round-arched windows, along with a smaller round-arched window at the tower. The east elevation consists of a two-bay gabled block at the center with blank flanking bays, and a modern flat-roofed vestry built at ground level.

The interior is stripped, featuring two stained glass patterned windows dedicated to the Smollett family. The graveyard contains a range of mid to late 19th-century grave monuments, including a Celtic cross and slab memorials.

The Smollett Mausoleum itself is designed in the Romanesque Revival style and has a shallow T-plan, straddling the rear wall. It is made of honey-coloured sandstone ashlar with ashlar dressings and features zoomorphic and figurative sculptures. The gabled entrance bay has a Romanesque door adorned with chevron moulding, colonnettes, a hoodmould, zoomorphic labelstops, and a plaque in the gablehead topped with a cross finial and grotesque figurative corbel. The mausoleum includes narrow bays with recessed niches, an arcaded blind window with a hoodmould and grotesque labelstops, and shows significant weathering on the left return. It has a grey slate roof with ashlar ridging.

Additionally, there is a war memorial made of rusticated granite with a battered base and a primitive Celtic cross. The gatepiers and railings consist of octagonal piers with depressed finialled caps, a low plinth wall, and arrowhead cast-iron railings.
