Happy 80th birthday to the trig pillar

On 18 April 1936 a group of surveyors gathered around a white concrete pillar in a field in Cold Ashby and began the retriangulation of Great Britain. That trig pillar is still standing 80 years on, along with thousands more around the country. We’re celebrating by sharing the story of the humble trig pillar, still much loved by walkers today, and giving you the chance to join our celebrations with The Trig Pillar Trail Challenge.
