Day Two - Part Two: PK Porthcurno Museum of Global Communications | West Cornwall Fully Loaded Cycle Tour - Carnaby Snaps
With the outbreak of World War II the facilities of PK Porthcurno were under threat and in 1941 miners were employed to build tunnels into the valley hillside to house the telegraphy equipment

These twenty four hour clocks are a prized possession of the museum and have a complex winding system behind them that still keeps them rotating today

Life inside the wireless room
Museum information plaque: Direct Printer 1940s
The adaptor on this direct printer reminded me of the old matrix printers you used to plug into 90's computer systems, difference was that this adaptor was huge in comparison!
A very helpful guide and long time resident of PK Porthcurno explained what all these fuses and how they are linked to the undersea cables, I must it was alittle confusing for to grasp but fascinating none the less!
This is one of the actual bombs dropped on Cornwall during World War Two, it fell nearby on Roskestal Farm in 1941

Museum information plaque: Training Poles
Mini training poles erected in the 1960s as part of the training facilities for the Cable & Wireless College. The height of the pole meant students did not need to use ladders
The Cable Hut c.1929 is where undersea telegraph cables came ashore from all corners of the world
The sandy beach at Porthcurno where the cables meet the sea
Eastern House c.1904 was the main building for the PK Porthcurno telegraph communications until 1970 and later became the training school until 1993, it is now the Museum of Global Communications
