St Mary's R.C. Church, 39-41 High Street, Lochee, Dundee

St Mary's Roman Catholic Church and Presbytery, located at 39 High Street, Lochee, Dundee, were designed by Joseph Aloysius Hansom and constructed in 1865. The buildings are executed in rubble masonry with ashlar dressings, demonstrating a remarkable Gothic Revival style.

The church is dominated by an octagonal five-stage chancel tower. It features five tall and two shorter windows with cusp-traceried designs, supported by clasping buttresses and flying buttresses at the base. The lower stage of the tower is battered. A facetted, stumpy spire rises from the tower, adorned with bands of fish-scale slates and a wrought-iron finial. A Lady Chapel is situated to the west, with a semi-circular apse featuring six cusped lights and a semi-conical roof. A traceried window is set in the west gable. The side elevations have steeply pitched slate roofs, a row of clerestory lights to the nave, and small, paired windows to the aisles, divided by buttresses rising from a battered base. The north gable features a central buttress with a niche and a blind arcade at ground level, which has been altered to create doors. Above this is a hoodmould with two lights and two quatrefoils. A timber bellcote sits at the apex of the gable. A porch is located at the northwest, featuring an original pointed arched, hoodmoulded door, a clasping buttress, and a single bay of west gable. A semi-octagonal projection extends to the east, featuring small geometric traceried windows, a facetted roof, and a wrought-iron finial.

The church interior exhibits notable constructional polychromy. Grey stone piers support yellow brick arcades with red sandstone bands. Engaged shafts support steep timber arch-braced roof trusses. Lean-to roofs are present in the aisles. The side walls feature a low, blind arcaded corbel table with depictions of the Stations of the Cross. The dark nave contrasts with the well-lit chancel, which has a high prismatic roof, stained glass, and a flamboyant addition by A.B. Wall of Cheltenham, dating to 1897. A similar altar is found in the arcaded Lady Chapel. Lower portions of the side walls, the Lady Chapel, and the blind arcade in the chancel are partially obscured by modern wooden panels. A gallery and a later organ are located at the rear.

The large, two-storey presbytery is asymmetrically aligned to High Street, with few right angles. The street-facing elevation has a large, pointed arched entrance set within a simply carved surround, flanked by quatrefoils and two-light openings. A canted bay facing the apse of the church, extending two bays to the east, is recessed at the first floor with a central wedge. The ground floor entrance has a shouldered arched door. The main ground floor windows are segmental arched with a transom bearing a mullion to the upper, painted section. The first floor has single-light transomed and cross windows, some with modern glazing. Gothic dormers are incorporated into the rear elevation; one lacks a mullion. The building is roofed with slate and has four stacks (one rebuilt, one missing). The interior has undergone some alterations, but Tudor chimneypieces and a panelled ceiling remain.
