Chilworth & St Martha's


This popular walk takes in the most prominent (and famous) remains of the Tillingbourne mills and climbs the steep hill to visit St Martha’s Church.

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 historic site is a Scheduled Ancient Monument and is owned and managed by Guildford Borough Council.  West Lodge has been “at risk” for a number of years but there is currently a funding initiative to purchase and conserve this building which forms the entrance to the Works from Blacksmith Lane. The plan is to use West Lodge as a base for the volunteer groups and the working parties within the Gunpowder Mills site as well as a fantastic and beautiful place for local history and educational groups to meet. With next year marking the centenary of when the Works finally closed, this is an ideal time to join our walk and view some of what makes this area so worth preserving. (More details HERE)


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. Having walked to the top, not only do you have the opportunity to see the panoramic views from the church but the graveyard itself is worth exploring – with several memorials to famous people, including Yvonne Arnaud.
