All you need is an interest in underground places - membership is not required!

UK Site Directory

UK Site Directory

Sub Brit has published a revised and updated version of our popular directory of underground sites across the UK that are open to the public. Sites range from Neolithic flint mines to nuclear bunkers. This new colour version now lists nearly 300 sites, with photographs of some key sites. Many sites are open year-round, admission to others is sometimes limited to special visits arranged by local groups. A brief description, location and contact details are listed for each site, along with a breakdown by county.
