[4] St Mary's is constructed in a combination of greenstone, ironstone and limestone coursed rubble.

The dressings are in limestone ashlar, there is some brickwork present, and part of the walls are rendered.

Its plan consists of a nave with a south aisle under one roof, a smaller chancel, and a southwest tower.

The bell openings have Y-tracery, the parapet is plain, and there is a pinnacle at each corner.

[1] Inside the church, the doorway leading to the tower has a pointed head.

In the south aisle are fragments of a stone coffin bearing the effigy of a 14th-century knight, with a lion at his feet.
