Originally a simple two-cell church, essentially Romanesque. The medieval portions are rubble wall, rendered, and painted white, rather upset by a large Victorian S transept and vestry, with a modern 2-bay arcade. The Romanesque features are a plain N door (behind a brick porch) and a late 12thc chancel arch.

Bramdean is recorded in the Domesday Book as a medium-sized settlement with a value to the lord of £3. The rectory was assessed at £5 in 1291.

Whether the arch was originally pointed is not clear, but the Early Gothic forms can be paralleled at nearby Swaythling, which certainly is of pointed form.
