[1] Inside the church are tall five-bay arcades with pointed arches carried on quatrefoil piers.

On the wall of the aisle is a re-set section of a reredos dated 1709, an 18th-century painting of the Holy Family, and elaborately decorated boards inscribed with the Ten Commandments.

On the floor beneath these objects is a long school desk carved with graffiti, and a 19th-century bier.

It was made in 1889 by the Casson Patent Organ Company, and restored in 2007 by Rodney Briscoe.
