Church of St Andrew

The Church of St Andrew is a Grade I listed building located on Church Street in Northborough. It dates from the late 12th to the 13th century and features a nave with four thin buttresses at the west end, topped by a gabled bellcote that has two moulded arch bell openings. The parapet is adorned with a dog tooth frieze and moulded coping. The 13th-century aisles include a north aisle with a chamfered doorway, two 17th-century straight-headed windows, and a 13th-century west window with Y-tracery. The south aisle has two 13th-century Y-traceried windows, while the east window features a quatrefoiled circle and a parapet with a frieze of small grotesques.

A notable 13th-century south doorway has two orders of colonettes and a heavily moulded arch. The 15th-century porch is marked by a four-centred arch. The decorated chancel includes reticulated traceried windows on the north and south sides, and a restored Perpendicular east window. A large south chantry chapel, built by Geoffrey or Henry Delamore around 1330-1350, is two bays long and features a large four-centred arch, a five-light south window with circular tracery between two polygonal turrets, and segmental arches on the east and west windows. The chapel is constructed of ashlar and has battlements and a ballflower frieze below. Beneath the chapel is a vaulted charnel house with bone shoots, and Mrs. Oliver Cromwell is buried there.

Inside, the church has 13th-century three-bay arcades supported by circular piers with circular capitals and abaci, along with double chamfered arches. The chancel arch is decorated with fillets on the responds, and one capital features carved foliage. The nave and chancel roofs have depressed tie beams. There are 15th-century sedilia and piscina in the south aisle, a rebuilt 17th-century altar rail, and a plain 15th-century octagonal font along with 19th-century and modern furnishings. A monument to James Claypole from 1594 is also present; the Claypole family owned Northborough Manor, and Oliver Cromwell's daughter married a Claypole, with his widow also residing in Northborough.
