Cramond

This guide to Cramond in Edinburgh corrects the story behind the concrete pyramids marching across the sand toward the island: not the anti-submarine 'dragon's teeth' most guidebooks claim, but a Second World War defense built for a different kind of enemy craft. You'll hear how engineers slotted reinforced panels between the blocks to form a continuous wall, and why the steel hawser wasn't threaded through until a year after the war ended. Time your crossing carefully and watch the tide before you set out.
