File:Averham, St Michael's church, Interior (24655230101).jpg

The church dates from the early 12th century onwards, with evidence of Norman herringbone masonry. The church was restored in the 19th century and again in 1907.

There is a western tower, aisleless nave, south porch and chancel. The tower is of two stages and is topped by a parapet with shields and eight crocketted pinnacles with gargoyles. The upper portion of the tower is later than the base, 14th to 15th century. There are six bells. The south porch dates from the early 16th century, and has its own gargoyles. There are coats of arms referring to Sir Thomas Sutton above the door. The inner doorway is 15th century. The chancel has Early English windows, and was lengthened around 1400. The screen dates from a similar time (although is much restored). The chancel has a barrel roof which was installed in 1858. Located on the north wall of the chancel adjacent to the altar, is a monument to Sir William Sutton, died 1611, and his wife Susannah. He is shown in the usual supine position with his hands in prayer alongside his wife. Unfortunately the hands were replaced after they were vandalised in 1984, and the monument was sprayed with paint. There is also a monument to Sir William's son, Robert, who died in 1668. His heart is said to be contained within the urn at the top.

There are several 19th-century stained-glass windows, and a two light window of mediaeval glass which was reset by J. H. Sutton of Brant Broughton, circa 1885.
