St Mary's Episcopal Church, Perth Road, Birnam

St Mary's Episcopal Church, located on Perth Road in Birnam, was designed by Richard Cromwell Carpenter and built in 1856-58, with William Slater overseeing the project. The tower belfry stage was added by James Ramsay in 1882, and a low north aisle and baptistery were built by Norman & Beddoe in 1883. The choir stalls were crafted by Rev Edward Sugden in 1889, and the church originally received an organ from Forster and Andrews in 1874, later rebuilt by John R Miller in 1908. This is a well-detailed Gothic church, notable for its unusually fine interior and Burne-Jones windows by William Morris & Co.

The church is constructed of squared, coursed, and snecked rubble with ashlar dressings. Architectural details include a raked base course, a band course, machicolation to the tower, angle buttresses, voussoirs, traceried windows, and chamfered reveals. The southwest corner features an entrance tower with a two-leaf timber door and a traceried oculus, which appears small in comparison to the projecting buttresses flanking it. The north aisle has Burne-Jones windows and squat buttresses under a swept roof with small ventilators. The southeast elevation displays the nave and chancel, the latter featuring a hoodmoulded recess below a two-light window, and a large three-light window to the northeast gable, which has a cross finial.

Diamond-pattern leaded lights are present throughout, featuring fine coloured glass or coloured margins. Grey slates cover the roof, with a brick chimney stack and ashlar-coped skews to the stepped roof.

The interior is particularly noteworthy for its decorative scheme, incorporating an open timber roof with simple cross bracing, limewashed walls in the nave and aisle, remnants of stencilling in the chancel, and a columned north arcade. There are also fixed timber pews and tiled floors. A moulded chancel arch incorporates carved head corbels, and a decorative stone septum with inset railings separates the sanctuary. The sanctuary contains a stone and marble reredos, a single-seat sedile, and a piscine. A carved oak pulpit and a circular carved stone font at the baptistery are also present.

Several significant stained glass windows are incorporated, including the Alexander and Evelyn Mary Low Memorial Windows in the north aisle, designed by Edward Burne-Jones and executed by Morris & Co. These windows depict 'King David and St John' (designed 1866 and 1869) and 'Ruth and Mary' (designed 1886, completed 1904). The east window displays a Crucifixion by C E Kempe (1895), and the south wall of the chancel features 'Moses and St John the Baptist' created by James Ballantine & Son (1864).
