Island Images - The Isle of Man in Pictures
This is the site of the WW2 RAF Radio Track Beam, a British copy of the Luftwaffe bombing beams used against the UK. I'm standing on the base of the transmitter building and the long track leads to the aerial site.  Judging by the distance away from the buildings it was probably radiating a very powerful signal!
