[2] The site of the church is recognised as a Scheduled Monument, and it stands within the earthworks of Stanwick Camp,[2] a settlement originating in the early Iron Age.

In the top stage are two-light bell openings, and the summit has a battlemented parapet.

Incorporated in the fabric of the south aisle are carved stones dating from the Anglo-Saxon and medieval periods.

In the north wall of the church are three two-light windows containing Decorated and Perpendicular tracery.

On the east wall of the chancel are boards painted with the Lord's Prayer, Creeds, and the Commandments.

[9] To the south of the porch are two memorials, one to William Newcomb who died in 1752,[10] and the other to Richard Slater dating from the early 18th century.

[12] To the north-northeast of the church are two wells built in the late 19th century for the Duke of Northumberland and possibly designed by Anthony Salvin.
