English: Towers of Telegraph, St. Mary's Looking from Pungies Lane towards three towers close together in the hamlet known as Telegraph. The granite round tower in the centre was built on the highest point of the island as a gun and semaphore tower soon after 1805 and later adapted as a signal station. In 1898 Marconi received radio signals here from Portcurno 30 miles away. A more modern coastguard transmitter mast is on the right and an inter island microwave telecoms link can be seen on the left.
