Quite often you hear a rumour about something and its just that. This turned out to be true! The area west of Salisbury was a massive training area in ww1,with a lot of Australians in particular. The pics show a tunnel that was built by soldiers practicing for mining operations on the western front,it took some finding as its hidden in deep undergrowth in the middle of no where. The modern frontage prevents entry and i have no idea of its purpose?(bats?),the tunnel was originally unlined as its through chalk.You can see daylight at the far end(not in the pic though!). I wonder if any of the lads who made it survived? Cheers Tig
