Ordnance depot dating to 1899 and used for storing cordite, guncotton and other materials for the army. The site consisted of 12 small magazines, each surrounded by an earth bank with woodland planted between them to minimize explosive potential. The site was originally developed by the navy to compensate for the loss of the Chattenden magazines to the army but by 1903 was united with the Chattaeden magazines under the navy to form Royal Naval Ordnance Depots.
