[1] When it was realised that there was no room for further expansion of the storage facilities at Upnor, a nearby site inland at Chattenden was purchased, and in 1875 five magazines were built on a hillside (the contours of which helped provide a natural traverse for security and protection).

[6] The 1870s magazines at Chattenden remain in situ (though vulnerable to subsidence - a problem first identified soon after their completion); they were latterly used for general storage.

[9] The Defence Explosive Ordnance Disposal School was housed in a separate complex (Lodge Hill Camp) along with the National Search Centre (a joint Ministry of Defence / Home Office facility providing training in Explosive Ordnance Disposal and search training for the police and other civilian agencies).

[9] Chattenden and Lodge Hill Training Areas continued to be used into the 21st century, preparing personnel for active service in Iraq and Afghanistan.

[2] In 2007 the Ministry of Defence designated the Military Land as a brownfield area for redevelopment for residential and light industrial use.

The Lodge Hill camp however is home to 85 singing male nightingales, which is over 1% of the entire UK population which stands at 6000.

[a] Nightingales migrate several thousand miles to West Africa and then return to the same tree, making biodiversity offsetting[b] inappropriate for the species.
