Welcome to Slough Caverns

This site is aimed at providing information regarding the newly discovered cavern system beneath Slough, Berkshire. Discovered during the construction of the new Tasco Superstore on Wellington Street, Slough Caverns is proving to be one of the largest natural cavern systems in Europe, if not the world.

Whilst not open to the public, this web site aims to provide interested parties with a virtual insight into this natural phenomenon.

13 March 2008 - I used to live at number 10 Chandos Street up to 1964 above and behind the Hairdressing shop and I remember we had a shed at the back where the coke for the Ideal range/boiler was stored. This would have been situated according to your details of the cavern above the Eastern part of the complex. I often wondered why the pile of Coke in the shed never seemed to reduce in size even though we used a couple of buckets full every day. Now I realise that it was being constantly topped up from below in some way.

I would be grateful if you could investigate this phenomena.

Can you register my name to join the expedition into the Caverns when 'Health & Safety' officers proclaim the cavern as safe to enter.

27 February 2008 - The opening of the Slough Caverns to the general public has been put on hold indefinatly as concerns are raised over the cavern systems safety in relation to the development and expansion of Slough Airport, a project which is already way behind schedule. In the meantime, Slough County Council have put forward a proposal to open the Hershell end of the system up to be used as the worlds largest underground carpark, thus relieving some of the strain on the towns vehicular overcrowding.

21/06/07 - Treacle seams have been found at depths of approximatly 4300ft. The seams similar to those found in cavern systems in the Lancashire Karst region have been rated good for industrial use but of insufficient quality for consumer consumption. The treacle which has a chemical viscocity similar to unrefined oil is said to be found in a sizable seam being fed from a deeper and possibly purer reservior in an as of yet uncharted region of the caverns.

04/01/07 - An elevator shaft has been commissioned to carry explorers 2.5 miles below the surface to the main cavern artury below Eton. The elevator shaft, said to be the largest in the world, will consist of 17 seperate shafts connected via staging posts and will allow explorers more speedy access to the heart of the cavern system. Currently the dangerous journey to the centre of the cavern system takes explorers 32 hours to reach via the existing natural system of fissures, crawlways and conduits. The shaft will lead into one of the smaller caves of a system of vast caverns which is just over 150m from floor to ceiling and will act as a staging post for further exploration.

21/11/06 - New rock bands discovered beneath the PFJ strata signify yet another significant and exciting discovery below rising sun formations and limestone deposits. The banding is thought to reflect a grouping of tectonic shifts in the Slough area roughly 2000 years before the first signs of Paleozoic activity has been traced back to previously. Much of the crystalised rock structure known as Coolus Strumus from the cooling of hot rock through liquids under pressure shows similarities with earlier geologic finds by Cleese in his works: The Anatomy Of Large Berkshire Geologic Formations 1889.

 

  • Slough Caverns were discovered by Micheal Fink of WS Atkins contractors during the construction of the new Tesco Megastore on Wellington Street in Slough, Berkshire England on 3rd November 2005.
  • The cavern system is still not fully charted but mapping to date shows at least 120 miles of cavern system stretching across an area of 5 square miles beneath Slough, Berkshire.
  • Archeological evidence has been discovered to indicate previous human inhabitation of the cavern system.
  • The cavern systems will be made open to the public, by special arrangement from as early as April 2009, weather permitting.
