glass window; the north, one at the north-east corner. The north chapel also contains a piscina. In the south chapel at the east wall, in an opening leading from the chapel to the chancel, is a blind doorway. At the south side is a piscina, an aumbry and a stoup. There is an elaborate canopied relief tomb niche, without tomb, with internal arch, with decorative bosses above, holding a cinquefoil with foliate bosses attached, and spandrels containing shields. The south chapel west stained glass window is c.1892. The north chapel has mirrored a more elaborate tomb niche including spandrels containing angels holding shields, and a castellated top with foliate cross. The church Perpendicular (Pevsner) or Decorated (Cox) octagonal font is c.1400, although re-cut, and includes a carving of Christ holding a chalice. Pevsner notes the church holding a chalice, cover and paten by David Willaume, dated 1711; a silver-gilt flagon by John Ward, dated 1713; a silver-gilt almsbasin by John Ward, dated 1714; a waiter by Daniel Smith & Robert Sharp, dated 1780; and a secular flagon by J. Denzilow, dated 1781. Memorials Within the north chapel, beneath the canopied niche on the north wall is an early 15th-century tomb memorial with two recumbent alabaster figures, attributed to Sir Richard Rickhill and his wife, Elizabeth. Cox attributes the tomb differently, to William Rickhill, Justice of the Common Pleas, and his wife Elizabeth, c.1410. Also in the north chapel is a table tomb with inlaid black marble panels, and a black marble lid with the inscription: "Sir Daniel De Ligne died the 20th day of March 1686 [and] The Lady Elizabeth his wife died the 25th of Aprill 1682", and heraldic shield above. The Flemish De Ligne family purchased the manor of Harlaxton in the 17th century. A marble wall memorial on the north chapel north wall, erected 1742, comprises an engraved plaque, this below an entablature with floriate details topped by a cockerel. Below the entablature, and either side, hangs gathered drapes. Below the plaque is an apron with Baroque scrollwork decoration, and a centred scroll-edged coat of arms. The arms contain three white cockerels on blue field to the left, and three gold lion heads on a black bar with five gold bars, on a red field to the right. The memorial is dedicated to Daniel de Ligne (died 12 December 1730) and Cadwallader Glynne (died 1 January 1736),
