Derelict concrete buildings from the second world war sit like the skeletons of dinosaurs with gaping holes where someone used to look through windows dotting our island that look now empty eye sockets in great big skulls lookout towers and brick built barracks and cinemas and pump stations and piers reach out to supply ships that now either turned to deep reefs for fish and sea creatures of myriad kinds or cut up and recycled into modern metal sea horses carrying a new generation of teenagers on to some kind of glory death and war.
