[4] The earliest part of the church is the chancel which is dated to the 13th century, due to the remnants of lancet windows in the Early English style and the double piscina in the south wall.

[2] In 1877, the north aisle was extended to form a new royal chapel to which Edmund's tomb was relocated from the chancel in the following year; Queen Victoria donated the window beneath which it now stands.

At the same time, an alabaster reredos designed by Joseph Clarke was erected behind the altar, and a new east window in the Perpendicular style was installed, revealing in the process the remains of the earliest lancets.

[2] The churchyard includes a monument to Elizabeth Hyde in the form of a Portland stone obelisk dating from 1801 or earlier,[5] and the grave of Christopher Augustus Cox (1889-1959), who was awarded the Victoria Cross in 1917 for his courage as a stretcher bearer under enemy fire during the First World War.

[6] The tomb consists of a plinth of Purbeck marble supporting sides of alabaster which are decorated with heraldic shields, thirteen of which survive of the original twenty.

A third body of a younger woman was also in the tomb, encased in lead,[7] who was tentatively identified at the time as Anne de Mortimer, the wife of Edmund's second son, Richard of Conisburgh, 3rd Earl of Cambridge.

[9] The main service of the week is Parish Eucharist on Sunday mornings which is streamed online, following traditional Anglican style of worship with robed choir.

Plans include replacing steps with ramps and level flooring, updating the heating system and removing the pews to allow different seating options.
