Clapham Common

Clapham Common is a triangular area of grassland of about 200 acres (0.8 km²) in size, situated between Clapham, Battersea and Balham in south London, England. Although most of it lies in the London Borough of Wandsworth it is wholly managed and maintained by the London Borough of Lambeth. It has three ponds and a paddling pool. The bushy regions of the common are used by homosexual men for cottaging activities.

The common has also been the site of the famous SW4 series of festivals and the live music oriented Get Loaded in the Park.

Clapham Common tube station and Clapham South tube station are on the edge of the park.
