Subterranea Britannica is a website devoted to underground sites in the UK, be they storage facilities, old kilns, chalk mines, military facilities from the cold war, astronomical observatories or even a precursor to the Channel Tunnel. It's full of photographs and informative articles and is a great resource for those interested in spaces beneath the earth. Dig deep and fill those gaps in your knowledge of British holes!
