If you are interested in World War II, Technology behind communication and how it changed the world, it is worth the long drive, it is fascinating. Porthcurno is a small coastal village where many submarines telegraph cables-transatlantic and to other locations came ashore from 1870 – 1970.
In WWII secret tunnels were dug by Cornish miners to house the entire building and the telegraph operation. These bomb proof/gas proof tunnels secured 14 cables out of the U.K. to its allies.
