Higham Ferrers is a small market town in the Nene valley, in the district of North Northamptonshire. It forms a single conurbation with Rushden to the N, and is 13 miles E of Northampton. The church stands to the E of the market square, and is the central building of a complex that also includes the Bede House to the S and the Chantry Chapel of All Souls immediately W of the W front. St Mary's is a large and imposing building of coursed limestone, part banded with ironstone, and limestone ashlar dressings. It has an aisled double nave, i.e. twin naves with aisles to N and S, and twin chancels, the N chancel built as a Lady Chapel. There is a S porch and a W tower with a tall spire. The original church was an aisled building with a W tower begun c.1220 and the tower completed c.1250. The N aisle was widened to the width of the nave c.1320, the Lady chapel added and the original chancel refenestrated with reticulated windows. The church is magnificent inside and out, with its tall spire, rebuilt after a collapse in 1631 and its spacious interior. The appearance owes much to the 15thc. work attributed to Henry Chichele, born in Higham Ferrers who became Archbishop of Canterbury. All of the fabric therefore postdates the 12thc, but the church houses a mysterious object in use as a holy water stoup, which is recorded here despite the lack of any known provenance.
