Gunpowder on the Tillingbourne
Chilworth's gunpowder mills trace back to 1625, when the East India Company set up works on the river here, using barges to bring raw materials in and take finished barrels away long before any road network existed.
From working mills to ancient monument
Production carried on at Chilworth into the modern era before the site finally closed, and the scattered remains of more than a hundred buildings are now protected as a Scheduled Ancient Monument.

Split between two parishes
The village itself is divided between the civil parishes of St Martha's and Shalford, both of which fall under Guildford Borough Council rather than Waverley.
