Magheradroll C of I Parish Church, Church Road, Ballynahinch, Co Down

Magheradroll Church of Ireland Parish Church is an irregular, mainly single-storey gothic parish church built in three distinct stages. The tower and spire date from 1772, the nave was (re)built in 1829, and the church was extended in 1870 with three large gabled side bays.

The tower and original portion of the nave are finished in rough cast with simple Georgian gothic character, while the 1870 extension is constructed in dark rock-faced rubble and is distinctly Victorian in style. The building is situated rather awkwardly in a hollow close to the roadside, surrounded to the west and south by a graveyard. It stands to the south of Ballynahinch town centre on the southwest side of Church Road.

The south gable of the main original portion of the nave features a panelled front door at its centre with a matching panelled wooden Tudor arch fanlight above. The door has moulded dressings and a moulded dripstone with label stops. Directly above is a stained glass pointed arch window with matching dressings and label stops. The gable has a stone parapet. Abutting to the right is the south side of the 1870 extension, which has a projecting porch at its centre with a steeply pitched hipped roof. The south face of the porch contains a gothic arched door opening with a moulded surround, while the east face has a small square-headed window with leaded panes.

The east elevation is mainly occupied by the 1870 extension, consisting of three joined gables each with a large gothic window featuring four lancets with reticulated tracery above. The windows and quoins are dressed in light coloured Portland stone. Between the roof pitches are two secret gutters, each with a cast iron rainwater hopper and downpipe.

The north elevation has the north face of the 1870 extension to the right and the gable of the original nave to the left. At the centre of this gable is a panel tracery window with four lancet lights in the lower section. The gable is buttressed and has a parapet with stone copings.

The west elevation contains the four-storey square tower of 1772 at its centre. To the right of the tower on the nave is a tall lancet window, with a small hipped roof single-storey extension further right. To the left of the tower is a lean-to single-storey projection, possibly added in the early twentieth century. The west face of this projection contains a pointed arch doorway with a plain fanlight above a modern panelled door, reached by a short flight of steps. The west face of the tower base also has a Tudor arch-headed door opening with a plain fanlight above a modern panelled door, set at the head of a short flight of stairs and protected by a gallows bracket canopy.

The ground floor south face of the tower is blank, while the north and east faces are built against the vestry and the nave. The upper faces are all identical. Each of the four floors is slightly set back, with each level reducing in size and featuring a projecting horizontal stone string course. The first floor has a small Y-tracery window, while each face of the second floor contains a small decorative opening with a blank slate panel. The third floor has a small gothic arch-headed window opening with a timber louvered frame. At each of the four corners of the battlemented parapet are pinnacles. An octagonal spire rises from the top of the parapet.

The walls of the original nave and tower are finished in unpainted rough cast, while the 1870 section is finished in squared dark field stone with sandstone and Portland stone dressings. The roof is covered with natural slate and rainwater goods are in cast iron.

At the roadside is a low boundary wall in rubble with granite coping, supporting simple wrought iron pointed-head railings. Two gateways in simple style, curved at the top, break the railings.
