Elder Memorial Free Church, Casselbank Street, Edinburgh

The Elder Memorial Free Church, built in 1899-1900 by Sydney Mitchell and Wilson, is a late Scottish Gothic-style aisled church located on Casselbank Street in Edinburgh. A brick church hall was added to the rear. The church is constructed primarily of cream-coloured sandstone, with squared and snecked stugged rubble walls and stugged and polished ashlar dressings. The hall is of variegated red brick with stugged ashlar dressings.

The northeast elevation, facing Casselbank Street, features a two-bay gabled porch to the right with a deeply chamfered ogival doorway and blind cusped tracery. A small two-light window sits above the doorway, with a taller, similarly detailed window to the right. Five bays comprise the aisle, each featuring broad, depressed-arched four-light windows with curvilinear tracery and divided by buttresses. A more recent, single-story, flat-roofed porch is situated on the outer left bay, incorporating a deeply chamfered doorway, a bipartite window, a boarded door, and a fanlight of three stepped lancets. The wallhead returns in steps to a gabled belfry, largely rendered in cement. A leaded, octagonal fleche is topped with an ogival dome, pinnacles, and a weathervane.

The southwest (rear) elevation is five bays wide, with the bay to the far left slightly recessed. A lean-to projection at ground floor level features a bipartite window, while a stepped tripartite window is directly above. The remaining bays have broad four-light windows with square-sectioned mullions and tracery. A single-story brick hall, rectangular in plan, adjoins the building at an angle to the right, displaying three tall, stepped windows in its northwest gable. The northwest elevation features a gabled design with a centrally placed tripartite window.

The windows are fitted with small, leaded panes featuring a yellow border. The roof is covered in green slate with red ridge tiles. Ashlar skews are present, with the west porch featuring triangular skews and gabletted skewputts.

Inside, the four-bay nave is characterized by an arcade of depressed arches supported by octagonal ashlar piers. The braced timber roof rises from foliate stone corbels, incorporating blind arcading to the braces. The aisles are barrel vaulted, with some modern replacements. A raked west gallery has plain panelling. The original organ was removed in the early 20th century, and the organ pulpit, featuring plain panelling and blind tracery, was repositioned on a raised east platform. Original pews remain, along with ornate ventilation grilles and elaborate wrought-iron hanging and wall lights. The hall, which is three-sided to the southeast, features a braced timber roof and two skylights.
