What is the Telegraph?
telegraph (Oxford English Dictionary definition)
noun a system or device for transmitting messages from a distance along a wire, especially one creating signals by making and breaking an electrical connection.

Why Porthcurno?
Porthcurno valley, in the far west of Cornwall, was the hub of international cable communications from 1870-1970 and a training college for the communications industry until 1993.
In WWII secret tunnels were dug by Cornish miners to house an underground building and the entire telegraph operations. These bomb proof/gas proof tunnels provided 14 secure cables out of the UK to its allies.
