St Peter and St Paul's Churchyard is a unique green space within the borough. The Churchyard, only a couple acres in size (8093.7 square meteres), was closed to new burials in the 1990s. It was decided between the church and the council, who became responsible for its maintenance on its closure, that the site would be best managed as a nature reserve.
The London Wildlife Trust took over the management of the site in 1997.
The area surrounding the church is maintained very much as gardens where nature can thrive but the emphasis is on formality. Further away from the church the gardens give way to an area of meadow where gravestones are found resting amongst spring and summer flowers. The Churchyard won a Green Flag Award in 2003.
