Bovevagh Presbyterian Church, Ballyquin Road, Camnish, Dungiven, Co Londonderry

Bovevagh Presbyterian Church is a substantial 19th-century building of distinctive "T" form, with a nave and transepts of practically equal length. The church stands close to the east bank of the River Roe, near the junction of the Ballyquin and Camnish roads.

The main structure has rendered walls beneath a steeply pitched natural slate roof with decorative red ridge tiles (some broken), valleys finished in lead. The roof pitch is approximately 50 degrees. A lean-to porch projects from the nave end, built of random rubble sandstone with a battered plinth. The porch has two pointed entrance doors in pairs, each with ashlar sandstone reveals and chamfering, and an unadorned barge stone without kneeler on each gablet. A single cusped pointed lancet window with central placement breaks the eaves of the porch's long wall, forming a gabled dormer with stone barges and a slated roof whose ridge finishes level with the lean-to roof. Gutters are fixed directly under the slate overhang with downpipes flanking the dormer on either side.

Above the porch, centred on the nave gable, sits a wheel window with four quatrefoils and a semi-circular hood moulding. The gable features simple barge stones with small moulded kneelers on each side that do not project above the barge line. Above the wheel window stands a double bellcote in ashlar sandstone, gabled in Early English style with unadorned bargestones and shouldered detailing. A small chamfered quatrefoil opening sits at the bellcote's apex. The bellcote is probably contemporary with the porch. Below the main gable apex runs a thin, slender louvred vent to the roofspace.

The nave and transepts are each two bays long, fitted with two cusped lancets per bay featuring leaded lights. The transept gables each contain three closely spaced cusped lancets, with small quatrefoils above towards the gable apex, fitted with semi-circular architraves and serving as vents to the roofspace. The west wall of the transepts, behind the pulpit, contains six cusped lancets. A small chimney stack with single pot rises on the south gable.

A substantial 20th-century hall extension adjoins the church on the west side, measuring seven bays long and two storeys high. It is gabled, slate-roofed, and rendered, with a further flat roof extension at the south end. The extension is separated from the church by a narrow gap with a passageway connection just north of the pulpit area; its first floor aligns with the church floor. The church appears to have no basement, though considerable ground crossfall exists across the site.

The graveyard, well-filled and now closed, occupies the site to the east and south. No graves lie between the buildings and the riverbank. To the north, a carpark has been formed. The boundary to Ballyquin Road features a random rubble wall with entrance gates and piers. Yew trees are scattered within the graveyard, and several mature trees stand on the south and west sides.
