Church of St Mary

The Church of St Mary is a parish church dating from the 13th century, with restorations carried out in 1849, 1876, and 1905 by Carbe. It is constructed of field and rubblestone with limestone dressings, topped with a plain tiled roof featuring crested ridge tiles and restored end parapets. The west end of the nave includes a double bellcote under a gable, which has a vesica opening in the spandrel and is supported by three carved stone corbels. The church has a plan comprising a nave and chancel.

The nave features diagonal buttressing at the southwest and northwest corners, along with a restored west window that consists of a single light in a pointed arch, complete with a moulded label and stops. A 19th-century gabled porch is present, featuring a two-centred outer arch with a label and stops, as well as diagonal buttressing. The inner arch is also two-centred and chamfered. The chancel has two 13th-century lancets in the south wall, which have modern labels, and reused moulded stone is incorporated into part of this wall. The rebuilt east window consists of three lights with similar stops, while the north wall also contains two 13th-century lancets.

Inside, the west wall has an original deep splay for the lancet window and similar splay features for the paired lancets in the south wall of the nave. The north window openings have modern rear openings. The chancel arch is two-centred and composed of two chamfered orders on chamfered responds with moulded capitals. There is a 19th-century organ bay and vestry on the west side of the nave. Original rear arches are present for the two lancets in the north and south chancel walls. A piscina from the 13th century features two bays in a two-centred arch. The font, also from the 13th century, has a square bowl with chamfered courses set on a modern stem and base.

On the west wall, there is a wall monument dedicated to James Fortrey, who died in 1719. He was the son of Samuel Fortrey of Fortreys Hall in Byal Fen, Chatteris parish, and served as a page of honour to Mary of Modena, Duchess of York, and wife of James II, as well as Groom of the Bedchamber to James II.
