Rhydymwyn Valley Works

A former chemical weapons factory in the UK producing pyro and mustard gas which later played a role in the development of the worlds first atomic bomb and whose huge underground storage tunnels were once considered as a location to store the nations gold reserves in times of war.

Some inaccuracies in the script....At 0:35 in the buildings shown were offices, washrooms, air raid shelters and mess rooms. At 1:23 the script states " This building produced mustard gas and pyro." This building (P5) was built to produce Pyro (the name given to a specific process to produce mustard gas ), but, did not produce any, the nearest to production it came was in the reconstitution of mustard gas produced elsewhere after storage problems were encountered. Mustard Gas was manufactured at 2 other buildings on the site (R3 and R4) using the Runcol process. At 1:58 the script reads "The pyro and Mustard Gas made in Buildings P4 / P5 was stored in underground tunnels." To repeat, no mustard gas , either Pyro or Runcol, was produced in P4 or P5 so could not have been stored in the tunnels. The tunnel storage was mainly used for storage of Mustard Gas produced at the Randle works (on Wigg Island, near Runcorn) and Springfields Works (Preston)

Great footage, where are the tunnels situated? Any ideas?

[@serenarchie123]

Awesome footage by the way...the tunnels used to house emergency mobile bakeries and water wagons a friend of mine used to keep the vehicles serviced in the 80s,its still a semi sensitive site today, and plenty of rumours from dumb to alien activities, a strange site indeed
