Ordnance Survey (OS) is celebrating the 80th anniversary of the triangulation pillar, most often known as a "trig pillar" or "trig point" and a welcome sight to many a walker as they reach the peak of their walk.

I love trig points and always tap them thankfully and affectionately. It is interesting to conjecture though, were it proposed today to erect some brutalist concrete pillars in prominent positions in some of the world's most beautiful scenery; would it be accepted?

I wonder if there was any opposition? I doubt it, but I'm about to start reading Map of a Nation so perhaps that will shed some insight.
I've just 'discovered' that the three trig points closest to my house are almost equidistant from my front door with only about 120m between the distance to the closest compared to the distance to the furthest.
How exciting is that? Very is the obvious answer.
Then TPs 4, 5 and 6 (which are about four times further away) only have about 250m between the distances. That's doubly exciting.
I'll save 7 and upwards until the weekend.

I can see the Arthur's Seat trig point from my window as I type this. If I stand at the window I can see Calton Hill, but the trig point is obscured by tree tops.

One more reference point and we should be able to locate crowriver....

...as long as he provides some distances or angles.
I think there are seven trig points I can see from my house (assuming powerful telescope eyes).

@cb, aye if I were to look from the back window with a telescope on a clear day there'd be some other trig points in Fife I could locate. Also if I were to go upstairs I could maybe find one in the Pentlands.
