Chilworth Gunpowder Works are a fascinating reminder of the importance of the Tillingbourne Valley’s industrial heritage.  Everything that you see onsite from the intricate maze of waterways to the raised central track has been created over almost 300 years of gunpowder manufacture. The mills were most extensive and productive in the 17th century and from the 1880’s to the end of World War I.


The beautiful St Martha’s Church is a listed grade II Historic building. Perched on the top of the hill on the North Downs Way National Trail, the building is accessible only by foot. It is the only church in Surrey to be on the Pilgrims’ Way and featured briefly in the 1944 film A Canterbury Tale.


Please note:   The walk around the gunpowder mills is fairly flat, but can be muddy and slippery if wet.  The climb up to St Martha’s is very steep and should only be attempted by fit walkers.  There are a few gates on this walk.  Most of the walk will be off-road. Stout foot wear is recommended and weather appropriate clothing plus sunscreen lotion if required.

Well behaved dogs welcome on leads. Not suitable for children.

We will finish the walk with an optional drink in the Percy Arms pub.
