Old St Bride's Parish Church, Douglas

Old St Bride's Parish Church in Douglas was built in 1781. Originally designed in a rectangular plan, it was altered in the earlier 19th century and again in 1868 by architect Charles MacGibbon of Edinburgh, resulting in its current T-plan shape. The church features coursed squared and roughly-drove rubble with rusticated quoins, along with later additions of stugged ashlar and rubble.

The original structure comprised five bays, with round-headed windows at the lower level and square windows at the gallery level. A low two-bay porch projects southeast from the central bay, and the flanking windows have been altered to become single, tall, round-headed windows. All round-headed doors and windows are adorned with pilastered jambs and keystones.

Later modifications include rectangular gallery stair projections to the northeast and southwest, each featuring a round-headed door with a fanlight and a round-headed window on the outer face. There is an inscribed datestone above the northeast door and rusticated quoins. The church was extended in the earlier 19th century by two bays from the northwest wall, with a narrower single bay extension beyond that includes a door.

The building has an eaves course, cornice, and piended slate roofs. Inside, there is a galleried interior and some leaded glass panels.
