Porthcurno Telegraph Museum

Main Display Room

Porthcurno's main display room, which occupies most of the South tunnel, documents the development of submarine telegraphy from the first Channel cable of 1850 to the outbreak of World War II, including amusing items of "social history". Rare specimens of cables, information on Brunel's 'Great Eastern' and the first Atlantic cable and many other unique items can be found in these display cases.

Look up (click and drag in the panorama window) to see a kite similar to one which was used to keep Marconi's wireless aerial in the air at Newfoundland, where the first transatlantic radio signal was received in 1901.
