The earliest feature of the church is Norman south doorway.
The next recognizable building phase is C14 from which time the chancel dates or was rebuilt.
A major remodelling took place in the C15 when the north aisle was added and the porch probably built.
The tower was struck by lightning in 1550 and rebuilt.
The date of the vestry is uncertain since it incorporates C17 features but these may have been re-used in the C19.
To its east is early C16 3-light granite mullion witn segmental heads and a hoodmould.
Beyond that is a C15 3-light mullion with ogee-headed lights and a hoodmould.
At the east end of the north wall is a C17 straight-headed 3-light mullion.
The vestry projects as a small wing from the north wall of the chancel with a cambered head doorway on its east side and a C17 mullion window on its north wall.
South wall of chancel has 2 apparently early C14 unrestored windows.
5-bay granite arcade to north aisle of Pevsner A-type piers with carved capitals and the moulding continuing on the 4- centred arches.
Late C19 carved pulpit, choir stalls and benches.
On north wall is a marble obelisk shaped memorial to Arscott Bickford of Dunsland who died 1771.
Adjoining it is a large slate wall memorial to members of the Bickford family who died at various times in the C18.
It is slate with a Corinthian column either side surmounted by a broken pediment with armorial shield at centre and winged angel's head below.
Beyond are 2 C19 marble memorials to the Heysetts of Baracott.
