St Nicholas' Church, Holm

St Nicholas' Church in Holm was rebuilt in 1781 and underwent renovations or another rebuild in 1818. It is a five-bay, symmetrical, rectangular-plan hall church with crowstepped gables and a plain design. A low, two-bay rectangular vestry is attached to the east end. The church is harled, and there is a walled churchyard surrounding it, which includes an outbuilding along the northern wall.

On the south elevation, the principal entrance features a squat, round-arched window with a horizontally aligned oval niche above it, located in the center bay. There are tall, round-arched windows on each side of the center bay, though these are blocked. The vestry has a window in each bay, set back to the outer right.

The west elevation, which serves as the entrance, has a deep-set round-arched door at the ground level with a blocked fanlight above it, situated in a full-height, slightly advanced narrow bay at the center. Each flanking bay has a high-set round-arched window below the gable.

The north elevation is a blank wall, while the east elevation features a vertically disposed sandstone heraldic panel centered below the gablehead stack of the advanced vestry. Above the main block, there is a stone crucifix at the gable apex. The south side has a small-pane timber-framed window with simple intersecting tracery, while other church windows are blocked. The vestry has 12-pane timber sash and case windows. The roof is tiled with Caithness stone, and there is a central square-plan timber vent. The vestry has old Orkney grey slate roofing and a corniced harled stack at the gable.

The interior was not seen in 1997. The walled churchyard features a rubble wall with a rubble cope enclosing a rectangular graveyard that contains predominantly 19th-century headstones. There is a small, rectangular shed with a boarded door on the west gable, a graded Caithness stone tiled roof, and a stone ridge. The south side has replacement square-plan squared rubble gatepiers topped with shallow domed concrete caps and timber gates.
