The plan consists of a nave and chancel, with a south porch and a north vestry.

In the north wall of the chancel are two two-light windows from the 15th century, and between them is a blocked doorway.

In the north wall of the nave are two 12th-century windows with semicircular heads, and a doorway from the same period.

The south porch is weatherboarded and it leads to a 12th-century doorway with a semicircular head and jambs in stone and Roman brick.

In the chancel are 15th-century piscinae and an oolite altar slab with carved crosses.
