Church of St Mary

The Church of St Mary, located on High Street in Stanwell, is a Grade I listed building dating back to the 15th century. It features a west tower, a three-bay nave, and a south aisle, with a later addition of a north aisle and porch. The chancel, which is early 14th century, has been rendered. The church underwent restoration by the architect Teulon in 1862 and again in 1903.

The tower is constructed with squared stone and flint in a roughly chequerwork pattern, and includes corner buttresses, a crenellated parapet, and a stair-turret on the south-west side. Its spire is covered with renewed shingles, and the roofs are finished with red tiles. The nave contains 19th-century windows designed in the style of around 1500, featuring flat heads and pairs of cusp-headed lights. The original north doorway retains damaged mouldings, while the north and west doors showcase impressive ironwork. There are 19th-century gabled chapels on both the north and south sides of the tower.

Inside, the church has a three-bay arcade with alternating piers and chalk arches, and a braced tie-beam roof that is moulded and supported on posts resting on carved corbels. The chancel features early 14th-century dado arcading, a pillar piscina, and an Easter sepulchre. A notable interior feature is the monument by Nicholas Stone dedicated to Lord and Lady Knyvett, who died in 1622; it is made of marble and depicts them kneeling beneath a columned and pedimented canopy. Additionally, there is a brass memorial in the chancel for Richard of Thorp, who died in 1408, and a memorial for Jane Hartley, who passed away in 1795.
