Anyone else interested in the defences associated with the two world wars? Spend your time studying airfields/pillboxes/air raid shelters, and want to share your findings with the rest of us? I do all the above when time permits, but a word of warning here. These places weren't designed to last 60+ years. They were built quickly (and cheaply)using materials now known to be dangerous, like asbestos. Add to that the fact that farmers have been using them to house livestock/chemicals etc, and they can be pretty dangerous places, especially underground sites. NEVER explore them alone! A few miles away from me, I have a site that was used for training troops for D-Day. It includes a replica seawall, German defences, trenches, a "shore" line and "assault craft". It's been well-battered by both artillery and small arms fire, and the only other similar site known to still exist is at Castlemartin in Wales. It can be seen on the NMR for Scotland at www.rcahms.gov.uk/, just add "Sheriffmuir,Perthshire", or "Atlantic Wall". It is presumed to be a replica of a real D-Day target, like "Hillman" and "Morris" which were built by the British 3rd Division at Moffat, in the Scottish borders. Something similar was built in wood and canvas at Muthill in Perthshire, but like Sheriffmuir its real-life counterpart on the Continent has yet to be identified. Anyone got some good sites near them? Yours in History, Gordon
