Bargrennan Church

Bargrennan Church is a rectangular-plan hall church built in 1839. It is constructed of rubble, with coursed and pinned stone on the south elevation, and features granite dressings, some of which are polished. The church has raised margins and round-arched windows fitted with fixed diamond-pane glazing. The roof is covered with small grey slates, and it has coped skews and skew blocks.

On the south entrance elevation, there is a shallow porch at the center, flanked by coped buttresses. The porch has a blocking course and a round-arched doorway with a two-leaf boarded door. Above the porch, there is a louvred oculus in the gablehead, and a gabled bellcote with a round-arched opening that houses a small bell, adorned with sawtooth skews and a fleur-de-lis finial.

The west elevation features three bays with regular fenestration, while the east elevation also has three bays with similar regular fenestration. The north elevation includes a half-piended vestry attached to the right, with a panelled door and fanlight to the right and a sash window to the left on the east return. There is a boarded door leading to an external closet to the right of center on the north side, and a corrugated iron lean-to attached to the west return. A small coped stack is located at the gablehead.

Inside, the church has a rectangular hall with painted plaster walls and boarded dadoes. The ceiling is flat and corniced. A pulpit is situated at the center of the north wall, and there is a timber communion table from 1969. A panelled door leads to the vestry on the left of the north wall, and a double-leaf door with leaded panes opens to the vestibule at the center of the south wall. The church contains timber pews and features a long case clock from 1857 positioned between the left and center windows on the east wall. A marble mural tablet commemorating the Rev John Barclay and the church restoration is located to the right on the north wall, while a marble war memorial mural tablet for the years 1914-1919 is found between the center and right windows on the west wall.

The church is marked by small granite gatepiers capped with pyramidal tops and ball finials.
