There is a reference to "St Mary in Buri" dated 1075 indicating the existance of an earlier church on this site.
The north porch is a fine example of C14 work with heavy timbers and 8-light open tracery on the sides.
The south porch is early C16 red brick with a crowstepped gable and a castellated parapet with machicolation.
The Waldegrave Chapel was built by Sir William Waldegrave circa 1514.
The nave has original roof corbels carved as angels.
