Centuries of gunpowder production
The gunpowder mills beside the Tillingbourne stream were operated by a series of companies, including the East India Company from the early seventeenth century, supplying gunpowder used well beyond Surrey before production finally ended after the First World War. The remains are now a scheduled ancient monument.
A valley village
Chilworth's houses sit in a narrow valley between wooded hillsides, a very different setting from the flatter land around Cranleigh, with the old industrial site now largely reclaimed by woodland and open access land.

Council
Planning and building control at Chilworth sits with Guildford Borough Council, reflecting its position closer to Guildford than to Cranleigh.
