The word weald is derived from Old Englishwald, a wooded upland. Harrow Weald Common is one of the remnants of the once extensive Forest of Middlesex. In the 18th century it was a haunt of highwaymen. Following the inclosure acts, one of the rights granted to the commoners was gravel extraction, and this took place on a large scale in the nineteenth century. In the 1880s there was an attempt to get government agreement to the sale of the Common, but a successful campaign to oppose this was supported by W. S. Gilbert, who lived locally at a house called Grim's Dyke. In 1899 the Metropolitan Commons (Harrow Weald) Supplemental Act revoked most of the rights of the commoners and a board of Conservators was set up to manage the Common. [3]
Harrow Weald Common is Common Land not owned by anyone, and in 1965 it was placed under the protection of Harrow Council.[4][5] The Harrow Weald Common Conservators are now a Friends Group which manage the site.[6]
