Telegraph Museum, Porthcurno, Cornwall.

The Museum is housed in a large white building, and associated tunnels, which formerly housed the shore terminal for Britain’s trans-ocean telegraph cables. It now contains exhibits about marine cables, telegraph equipment, etc. If you are interested in electronics or the history of technology, you should find this a rewarding visit. Don’t underestimate the time required to look at everything inside – I allowed two hours and found that this wasn’t long enough. If you are parking in the car-park between the Museum and the beach, I recommend that you pay for 3 hours’ parking. Note that should you need to lose the rest of the family for two or three hours, a beach and coastal walks are nearby.
