To either side of the chancel arch are 12th-century blind arcades which may have been originally intended as reredoses for side altars. There are round-headed Norman windows in the nave.
There are more Norman carvings in the south aisle, where you will find a set of nine carved corbels with a variety of designs including a horse's head, human heads, and an odd collection of beasts.
There is further Norman carving on the exterior east wall of the south aisle, where you can easily view re-used stones showing Norman sawtooth carvings.
Other features include a striking 14th-century tower with spire, late medieval aisled nave and clerestory, and a large Perpendicular east window. There is a 13th-century font and several monuments to members of the Cecil family of nearby Burghley House.
North of the church is the site of Wakerley Manor House. The church is no longer used for regular worship and is in the care of the Churches Conservation Trust. It is normally open daily to visitors.
