About

By Brook ward encompasses a rural portion of northwestern Wiltshire, characterised by its rolling farmland and the small river valleys from which it takes its name. The area includes several villages and hamlets, such as Box and Colerne, set within a landscape of fields and woodlands. Settlement is dispersed, with a focus on agriculture and local community life, away from major urban centres.

The geography is defined by the By Brook river and its tributaries, which have carved gentle valleys through the limestone uplands. A notable feature is the presence of the Box Tunnel, a significant 19th-century railway engineering project designed by Isambard Kingdom Brunel, which passes beneath the area. This quiet, pastoral ward is part of the larger Cotswolds National Landscape.
