Church consists of W tower and nave of the 13thc. and a S arcade of 14thc. date. The vestry may be of the 15thc. based on the window form; the chancel dates from the 1863 renovation by Edward Trollope, rector here from 1843-93. The S porch may be of the 19thc. as well. The W doorway of the W tower dates to c. 1200. There are also three reset 12thc. fragments in the vestry and one in the nave's N wall.

There is no mention of a church here in 1086 but D. Owen cites a Peterborough Dean and Chapter MS (#23) that records the foundation of an independent chapel in the 12thc. at 'Roxholme in Leasingham ' Whether or not this chapel was on the same site as the present day church is not known.

The W doorway probably dates to c.1200. The imposts of the doorway extend to the L and R all the way to the tower setback buttresses. They are made of separate pieces of stone from the capitals below or the arches above them The deeply undercut hollow is similar to that in the 13thc. string courses on the upper stages of the tower; the imposts may be later insertions into the doorway. The W window in the vestry is Perpendicular and may provide the date for the wall into which are reset fragments IV.5.C. i-iv as well as an Anglo-Saxon interlace fragment.
