The church has an elaborate S doorway of c1175, decorated with beakheads and complex chevron. In the nave the N and S arcades are late Norman in style, though their present appearance owes more to the restoration by William Butterfield in 1850. A stringcourse on the east wall of the chancel also dates from the 12th century and may indicate that the body of the chancel is Norman, although it was altered in the 14th century. The font also dates from the 12th century and is very elaborate with apostles set in a blind arcade. All this work is likely to have been done after the church was granted to Llanthony Priory (Gloucesterhsire) in 1167. The S porch, which cuts across the edges of the 12th-century door, was added in the 15th century.

Walter of Gloucester, the lord of the manor who died before 1129, granted half his tithes in Chirton to St Owen’s Church in Gloucester. In 1167 the whole church was granted to Llanthony in Gloucester (VCH X, 69).

Although the bowl of the font is very elaborate, the carving is not of top quality.
