About the event

Description of walk:  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 was 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.

Not only will we visit the main "Middle Works" but our walk will also take in Chilworth Vineyard plus the site of the less visited "Lower Works" where the original gunpowder manufactories were established.

Your knowledgeable guide will stop frequently to tell you more about the manufacturing processes and some of the historical highlights of the site.
