Telegraph Tower, Telegraph Road, St Marys, Isles of Scilly
This defensive gun tower and coastguards look out was built in 1803. It was proposed and designed by Major Daniel Lyman. It was one of 3 gun towers built on St. Marys by Lyman. All were intended to accommodate 8-10 men and mount a 32 pounder carronade (cannon) at the top. It was also where one of the first radio transmissions was received: "It was at this tower about 1898 that Guiglielmo Marconi heard wireless signals transmitted from Porthcurno, in south-west Cornwall, thirty miles distant".
