The London Borough of Bexley is a London borough in south east London and forms part of Outer London. The borough is twinned with Evry in France and with Arnsberg in Germany.
The borough was formed in 1965 by the merger of the former area of the Municipal Borough of Bexley, the Municipal Borough of Erith and the Crayford Urban District with half of Chislehurst and Sidcup Urban District.
Although part of suburban London, Bexley includes much open land. The line of higher land, mostly heathland, which follows the course of the River Thames, crosses the borough in Belvedere, where it is named Lessness Heath. In the woodlands on this heath lie the ruins of Lesnes Abbey.
Danson Park, in Welling, and Hall Place Gardens near Bexley provide public open spaces. Renovated Danson House is now open to the public. To the south of the borough, Foots Cray Meadows flank the River Cray, which joins the River Darent north of Dartford and flows through the borough.
