Baptist Church, King Street East, Helensburgh

The Baptist Church on King Street East in Helensburgh was designed by D Abercrombie in 1886. This rectangular-plan, three-bay Gothic church features a tower at the southeast corner, along with a two-storey church hall and vestry at the rear. The building is constructed from squared, stugged, and snecked cream sandstone, with droved ashlar dressings. Architectural details include base and eaves courses, pointed-arch windows, chamfered arrises, and hoodmoulds with floreate label-stops.

The south elevation facing King Street East has a tall gabled bay in the center, with the tower on the outer right and an aisle window on the outer left. There is a four-centred arch doorway in the center, featuring chamfered reveals and two-leaf boarded doors, set within an advanced gabled surround that has offset piers, an ashlar coped skew, bracketted skewputts, and a floreate finial at the gable apex. Above the doorway is a tall pointed-arch window with three-light cusped geometric tracery and a small niche at the gablehead. To the outer left is a lower single bay with a lancet window, separated from the center bay by an offset buttress, with an angle buttress flanking to the left.

The tower is two stages high, with an octagonal drum and an ashlar finialled spire. It features offset diagonal buttresses topped with pyramidal ashlar finials above the second stage. The south elevation has a Y-tracery window at the ground level and an oculus above with quatrefoil tracery, along with a hoodmould course above. The west elevation mirrors this with a similarly detailed oculus at the second stage. The drum has narrow round-headed louvered lucarnes on the south, east, and west sides, with a corbelled course above that steps up to gablets over the lucarnes.

The west and east elevations have five windows with Y-tracery, and a door to the vestry is located on the far left of the west elevation, with a window above it on the first floor featuring etched glazing depicting the River Jordan. The east elevation has two windows for the vestry and one window for the church hall above on the first floor.

The church features lead diamond pane glazing and has a grey slate roof with ashlar coped skews and bracketted skewputts.

Inside, the church is simply furnished with timber benches and has Gothic decoration on the reredos. The west window contains stained glass from 1906 that celebrates the foundation of the Zenana Mission in India by Rev John Sale.
