St Bartholomew's is constructed in stone rubble with tile roofs. Its plan consists of a nave and chancel built in the 12th century, a south aisle and a north chapel built in the 14th century, and a south porch of the 15th century. The south aisle is in three bays between which are stepped buttresses. The middle bay contains a pair of lancet windows. In the easternmost of the bays has a two-light window, and in the western bay is the south doorway. The porch is arched, and in each side of it are two-light windows. The west window of the aisle consists of two lancets, and at the east end is a three-light window. The west window of the nave has four lights. On the north wall are two buttresses, and it contains two 12th-century round-headed windows, one of which is partly obscured by a buttress. The chapel has a four-light north window, and three-light windows on the east and west sides. The south wall of the chancel is in three bays. It contains a priest's door, with a two-light window on each side. The east window has four lights, and below it are a two-light mullioned window and the head of a doorway leading to a vault.
Interior
Inside the church, the south arcade has three bays and the arcade between the chancel and the chapel has two bays. In the south wall of the aisle is a piscina, and against its west wall is a 13th-century coffin lid inscribed with a foliated cross. Under the north window of the chapel is a tomb recess. In the nave and aisle are box pews from the 17th century. Elsewhere in the church are benches, and there is an 18th-century family pew in the chapel under a canopy. There are fragments of 14th-century glass in many of the windows. In the chancel are six hatchments on the walls, and 18th-century memorial slabs on the floor.
Tower
To the east of the church is a detached tower dating from the 14th century. Some restoration was carried out on it during the 19th century. It has a square plan and is surmounted by a slate pyramidal roof with a weathervane. The tower is in three stages. In the lowest stage is an arched entrance on the west side. There are square-headed windows in the east and south sides in both the lowest and the middle stages. The upper stage contains two-light arched bell openings on the north, south and east sides. The tower has been designated separately as a Grade I listed building.
