Harrow Weald Common

Harrow Weald Common is an 18-hectare green space in the London Borough of Harrow, made up of woodland, heath and pasture. It was once part of a much larger ancient forest called the Forest of Middlesex. In the 18th century the area became known for highwaymen who used its secluded paths. Later, gravel was dug here on a large scale after the Inclosure Acts gave commoners that right. The commoners’ rights were reduced in 1899 when a board of Conservators took over management. The common is still owned by no one and is protected by Harrow Council. A group called the Harrow Weald Common Conservators now looks after the land. Nearby lies Grim’s Dyke Open Space, which contains an old earthwork called Grim’s Dyke or Grim’s Ditch. This three-mile earthwork may date from the fifth or sixth centuries, though its purpose remains unknown. Other nearby sites include the City Open Space and Bentley Priory Nature Reserve. Paths lead into the common from Common Road and Old Redding. Inside, visitors find quiet woodland walks and open heathland views. The varied habitats support a wide range of wildlife. The site also links to the longer Grim’s Dyke earthwork, offering a chance to explore ancient earthworks alongside modern green space.
