The church of St Michael may have originated in the 14th century.  The south aisle was added in the 16th century and repaired in the late 17th century. Refurbishments in the 18th century included the addition of box pews and the west gallery, and this period is reflected most strongly in the current character of the church. Work in the 19th century included the restoration of the chancel and replacement windows.

Graffiti has been found on the outer arch of the north porch, door and window openings within the tower, the gallery, the lead of the tower roof and the lead down-pipe at the east end of the chancel.  The box pews obscure the access to the aisle piers, but where visible, the piers seem to have no graffiti.
