The Harrow Weald Common, Grim's Dyke Open Space City Open Space 9358

Brief Description

Harrow Weald Common is a remnant of the once extensive woodland of the Forest of Middlesex. Grim's Dyke Open Space is named after the ancient earthwork that runs for 3 miles between Harrow Weald Common and Pinner Green, its original purpose unknown.


Following the Enclosure Acts, gravel extraction was granted as one of the common rights of Harrow parishioners, and this industry was carried on until the late C19th. Adjacent to the common is an area known as The City Open Space, once the site of cottages built for employees of the brick and tile works.
