St Mary's Church, Grandtully

A long, low, rectangular, gabled church which dates from around 1533 and which was extended in 1636. The building is limewashed rubble and has a single, off-centre rectangular opening with a boarded timber entrance door to the north elevation and small windows to both gables. The south elevation has a rectangular door with flanking window openings to the far left.

The window opening in the east gable has rounded window jambs and a lintel of around 1636, carved with the initials SWS and DAM (Sir William Stewart and Dame Agnes Moncrieff)

The building has graded grey slates and raised skews. There are projecting stones on each of the skews at the west end and a stone finial at the apex.

The interior was seen in 2016. The building is unfurnished and has two sections, divided by a stone wall. There is an exposed timber roof to the west end. The east end has an elaborately painted, barrel vaulted, pine timber ceiling which dates to around 1636 and has 28 roundels of varying shapes and sizes depicting saints, biblical scenes and the achievements of the Stewart family interspersed with floral, fruit and angel motifs. These are arranged around a central panel which depicts a resurrection scene. There is a small, open stone aumbry on the east wall and another, larger one on the south wall, with a timber door. There is a concrete floor.

There is a square churchyard to the south of the church. This has a tall, rubble boundary wall to its west and south and a pair of square-plan, coped gatepiers with a metal gate at the northwest, close to the church. The gravestones are mainly 19th century, some with carvings and one obelisk. One stone at the west of the churchyard is dated 1784 and is for a James Thomson. This has a carved angel head, and a depiction of Abraham and Isaac.

A small, rectangular grassy area lies to the north of the church. It is bounded with a rubble wall with curved corners. There is a pair of square gatepiers with loose stone slabs as coping stones situated opposite the entrance door to the church. Metal gates are situated between these gatepiers and also at the west end of the boundary wall.
