The Cann tunnel was built in the early 1820’s as part of the Plymouth & Dartmoor railway. Used to transport granite from the kings & swell tor quarries from the moor to Sutton pool, Plymouth.

In 1916 all the track was removed…..

During the second world war the Cann tunnel was reused and a contract was tendered to turn it into a deep shelter for 3000 essential dockyard workers…..they would essentially move into here for the duration of the war….

Evidence of beds & some sort of sick bay still exist, as do baffle (“blast walls†to prevent a direct hit killing all in the tunnel)

Also there are a few service tunnels above, old electric light remains and piped water…

We’ve been working on this one for a year or so, and finally it welcomed us in for a short period….literally spent hours and hours, loads of hard work, and even blood, to sort access….

Nemesis and the Kernow expeditionary force were in first… Access secure…we toasted with a beer & dare say we woke one or two people up with a txt in the early hours!

The group visit was sorted….

Visited with Nemesis, Scrub, Scotty, Sarah, MrB, The Stig & Lycos…..

we had to work for this one....
