Saltbox Hill

About

Saltbox Hill is a 22.2 biological Site of Special Scientific Interest in three separate areas in Biggin Hill in the London Borough of Bromley. One area of 6.9 hectares is owned and managed by the London Wildlife Trust. It is also a Site of Metropolitan Importance. It is a steeply sloping 55 acre biological site, which is close to Charles Darwin's home, Down House, and inspired him and provided him with a picnic place.

Much of it is chalk grassland which is rich in plants which are rare in Greater London, and it is one of only two sites in London which has the dark green fritillary butterfly. Ten species of orchid and over thirty of butterflies have been recorded. The site also has an area of woodland.
