Our Triangulation Pillar design print features a technical cross-section of a trig point. Perfect for the outdoor lover or hiking fanatic.

A familiar sight on hilltops across the UK, trig points (or 'triangulation stations') are beloved by outdoor lovers. There were once 6,500+ trig pillars in the UK, built by the Ordinance Survey. The pillar was devised by Brig Martin Hotine in the 1930s to provide a base for the theodolites used by the surveyors. When all the trig points were in place, it was possible in clear weather to see at least two other trig points from any one trig point. Although the stations are no longer required for surveying purposes, hikers love them as navigation aids and, of course, for marking the achievement of reaching the summit.

This design is printed using a Risograph, a stencil and ink process similar to screen printing. Risography gives an added texture and charm - and, here, adds to the vintage blueprint feel. 

  • One colour risograph, printed on premium grade green 170gsm paper.
