The Unsung Heroes of the British Landscape: Why Trig Points Deserve Our Attention
There’s something quietly profound about stumbling upon a trig point while hiking through the British countryside. These unassuming concrete pillars, often no taller than a person, feel like whispers from the past—relics of a time when mapping the world required ingenuity, patience, and a bit of mathematical magic. But what makes these trig points truly fascinating is how they’ve evolved from functional tools into cultural icons. Personally, I think their story is a perfect metaphor for how technology shapes our relationship with the landscape—and how we choose to remember it.
From Mapping Tools to Cultural Landmarks
Trig points, or triangulation pillars, were once the backbone of Britain’s mapping system. Designed by Brig Martin Hotine in the mid-20th century, they formed a network of 6,500 points that allowed surveyors to map the country with unprecedented precision. What many people don’t realize is that these pillars were part of a larger project called the Retriangulation of Great Britain—a monumental effort that laid the groundwork for modern cartography. But here’s the irony: while GPS and drones have rendered them obsolete, trig points have taken on a new life as cultural landmarks.
In my opinion, this transformation is what makes them so intriguing. They’re no longer just tools; they’re symbols of a bygone era, cherished by walkers, photographers, and even niche enthusiasts who engage in “trig-bagging”—the hobby of visiting every single one. If you take a step back and think about it, this shift reflects a broader trend: how we repurpose old technology into something emotional, nostalgic, and deeply human.
Why Listing Them Matters
The Twentieth Century Society (C20) recently applied for Grade II-listed status for the first and last trig points ever built—one in Cold Ashby, Northamptonshire, and the other in Thorny Gale, Cumbria. On the surface, this might seem like a small gesture, but it raises a deeper question: what do we choose to preserve, and why?
From my perspective, listing these trig points isn’t just about protecting concrete pillars; it’s about acknowledging the stories they tell. They’re reminders of a time when mapping the world was a labor of love, not just a click on a smartphone. What this really suggests is that even the most utilitarian objects can become vessels of cultural meaning—if we let them.
The Human Connection to Obsolete Technology
One thing that immediately stands out is how trig points have become emotional touchstones for so many people. Bill Bryson, in his book The Road to Little Dribbling, called them one of his “favorite British items.” They’ve inspired record labels, sparked artistic tributes, and even become focal points for group photos. A detail that I find especially interesting is how their design—simple, functional, yet oddly elegant—has resonated across generations.
This raises another point: why do we cling to obsolete technology? Is it nostalgia, or something deeper? Personally, I think it’s about the stories these objects carry. Trig points aren’t just about mapping; they’re about the people who built them, the surveyors who used them, and the walkers who still seek them out today. They’re a bridge between the past and the present, a reminder that progress doesn’t always mean leaving things behind.
The Future of Trig Points: Preservation or Oblivion?
Hundreds of trig points have already been lost to development, farming, and erosion. In the 1990s, the Ordnance Survey even considered demolishing them to save costs—a plan that was thankfully scrapped after public outcry. But their future is still uncertain. Local groups now maintain many of them, but without official protection, they remain vulnerable.
What makes this particularly fascinating is how their fate mirrors broader debates about heritage. Should we preserve everything, or let some things fade into history? In my opinion, trig points deserve protection not just because of their historical significance, but because of what they represent: the intersection of human ingenuity, cultural memory, and our enduring connection to the land.
A Modest Triumph
Catherine Croft, director of C20, said it best: “Nothing beats the modest triumph of standing on top of a trig point in a brisk wind.” That’s exactly what these pillars embody—a quiet, unassuming triumph. They’re not grand monuments, but they’ve earned their place in Britain’s cultural landscape.
As we celebrate the 90th anniversary of the Retriangulation of Great Britain, I hope we recognize trig points for what they truly are: not just concrete pillars, but markers of our shared history. They’re a testament to the idea that even the most functional objects can become something more—if we choose to see them that way.
So, the next time you spot a trig point on a hilltop, take a moment to appreciate it. It’s more than just a relic of the past; it’s a reminder of how far we’ve come—and how much we still value the stories that connect us to the land.
