Today is the 83rd anniversary of the first use of an Ordnance Survey trig pillar, so the perfect time to catch up with Britain’s top trig-bagger, Rob Woodall, on his latest achievement.
I bagged my final Welsh trig pillar in 2008 – sort of. At that time, I counted 660 trig pillars still surviving in Wales, and Red Hill, S6561, east of Builth Wells was my last, on a blustery August day. We celebrated with a Balvenie single malt (somehow not a Penderyn).
But had I really finished? The OS originally built 684 pillars in Wales – what about the others? At that time, I was focused on extant pillars, trying to get around as many trigs as I could before they were lost to housing developments, road construction, farming operations and the like. I’d visited all the remaining English, Isle of Man and Scottish pillars by 2016, so it was time to think about visiting the remaining vacant trig sites. Some were simply in-situ replacements, the pillars being rebuilt on the same site, with the same flush bracket or occasionally a new one. Sites that used to have a trig pillar, aren’t inherently as interesting to the bagger as those where there’s something to look for, but the scenery is still there (if it hasn’t been built on), and in some cases, the pillars weren’t quite as dead as we thought:
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.
