St Mary's Church, St Mary's Street, Dumfries

St Mary's Church, located on St Mary's Street in Dumfries, is a rectangular-plan, five-bay Gothic church designed by John Henderson of Edinburgh between 1837 and 1839. The church features a remodelled interior and a narrow chancel added around 1878, along with porches and a vestry positioned in the re-entrant angles. The exterior is constructed of red ashlar, with the principal south gable elevation facing St Mary Street divided by pinnacled buttresses into the nave and aisles. It has a pointed central doorway set in a shallow porch, with three tall lights above that include secondary glazing to protect the leaded windows, and timber cusping. The pierced parapet connects to a two-stage square apex belfry topped with a spire. There are doors at the south end of both flank walls, and the church is covered with slate roofs.

Inside, the church was renovated and re-seated in 1878 by the Crombie brothers. It features a gallery on three sides with a cusped-panelled front, supported by clustered cast-iron columns. The upper tier columns have foliated capitals that support a thin arcade separating the nave and aisles. The ceilings are timber, and there are leaded windows, including a memorial to Captain James Anderson of the "Great Eastern." Notable artists involved in the windows include Wm Meikle and Sons, and J T Stewart and J E C Carr. The church also contains a good Gothic brass lectern from 1907 and an organ by J J Binns of Leeds.

The churchyard is bordered by a continuous series of headstones, featuring many impressive monuments, mostly with classical details and some with pediments. It serves as the burial place of Captain James Anderson of the "Great Eastern." Near the main church door, there are fragments of Christopher's chapel and a sundial dated 1777 on a later pedestal. The site is marked by massive gatepiers at the roadside, along with retaining walls, steps, and cast-iron gates.
