and a two-light mullioned window at a high level. In the south wall is a three-light window, two blocked windows, and a blocked priest's doorway with a round arch. In the nave is a four-light window on the north side, and in the south wall a Tudor-arched door flanked by two-light windows. Interior The chancel arch is Norman in style. It is completely rendered, other than the string courses between the tops of the piers and the bases of the arches. When the rendering was removed from the string courses by the Upper Nene Archaeological Society, it was discovered that they were decorated with carvings. The carvings include sawtooth patterns, lozenge motifs, and depictions of a snake and birds. It has been suggested that they are in Viking style, and were possibly re-used from a former churchyard cross. However this has been refuted by Kathryn Morrison who expresses the opinion that the carvings date from the late 11th or early 12th century, and that an earlier date is "impossible". She also states that "the suggestion that the carvings are from a churchyard cross is difficult to substantiate". Elsewhere in the church, the chancel contains a sedilia, a piscina and an aumbry. The font is inserted into the north pier of the tower arch, and consists of a bowl on a polygonal stem. Also in the church are two hatchments, and memorials. There is one bell, cast by Henry Penn of Peterborough in 1710. The church plate includes a cup and paten dated 1860.
