We knew Windmill Farm Nature Reserve had World War II buildings scattered across the site, associated with nearby Predannack Airfield. The best preserved of these are three pill boxes situated near the information centre; however, it was not until we started to look more carefully at the hedgerows as part of our hedge laying and coppicing programme that we discovered more archaeological gems. Four more pill boxes were unearthed that we had no idea existed. Two of them sit side by side on a Cornish hedge. The hedge was coppiced in the winter, and the pill boxes can now see the light of day once more and look to be in excellent condition.
