I managed to get up the hills despite the weather, and photograph this WW2 bombing decoy. It's one of a series of bombing decoys called starfish sites, which used an ingenious variety of apparatus to simulate everything from unblacked-out skylights to city blocks ablaze. This one protected the former burghs of Kilsyth (to the south) and Denny (to the east, both of which had many iron foundries. This is looking down the entrance passage from inside... This divided the concrete bunker into three compartments. On the left was the crew shelter, and this view shows the escape hatch. There is also evidence of wall-mounted furniture in here... ...And this is the hatches exit on the roof... The other room held the generator equipment... This probably supplied power to a variety of pyrotechnics at a safe distance further across the moor. There is another well-preserved decoy site about 10 miles west of here, Craigmaddie Moor, which was the main decoy for Glasgow and attracted a few bombs during the Clydebank Blitz of 1941.
