  • Night ascent. Trig on path from car park. A superbly detailed info board nearby explains all about trig pillars, what they are, their shape (truncated square pyramids tapering towards the top),how they were used with a theodolite for calculating angles from which distances can be calculated by a construction of a system of triangles which could then be referenced back to a single baseline to construct a highly accurate measurement system that covered the entire country. and the fact that form each trig pillar at least two others should be visible.(subsequent vegetation growth often makes this not possible)
