Autumn Meeting and Visits - Saturday 13th and Sunday 14th October 2012

Booking is now open for the Autumn Meeting and Visits in Liverpool.

If you have never been to a Sub Brit meeting before, they are a tremendous opportunity to meet and network with fellow enthusiasts and learn about new sites in a relaxed setting.

For the first time, we have combined the usual talks with visits to a variety of sites.

UK Site Directory

UK Site Directory

Sub Brit has just published a directory of around 250 underground sites in the UK that are open to the public. Sites range from Neolithic flint mines to nuclear bunkers. 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.


Delivery of this item may take up to 14 days.

Help Save Wartling ROTOR Bunker - Donate Now

Sub Brit is currently trying to repair major leaks in the derelict Wartling ROTOR Bunker. Left unchecked, the bunker will slowly fill with water, destroying another of these rare Cold War survivors. The work is done by volunteers and is entirely funded by donations.

If the Wartling project becomes over-subscribed then I am happy for my donation to be added to Sub Brit general funds and used in other ways to protect our underground heritage.
