Steven Heaton has an excellent web site called “UK submarine cable landings & cable stations“. He documents and illustrates all the places in the UK where submarine cables come ashore and where their landing stations (the buildings which house the junction points) are.
Coming from Bude, I was obviously very interested to see Steven’s various posts about such cables around the Bude area, which you can see here, here, here, here, here, here, here, here, here and here.
There’s a brilliant Google earth style map here which shows many of the submarine cable routes.
