Built between 1936–1962, over 6,500 trig points formed the backbone of Britain’s mapping system. They are historic, cultural, and landscape icons for walkers and communities. Many are now damaged or lost, with no consistent protection. Without action, we risk losing these unique markers of scientific achievement and national heritage forever.
