Greater London OS Trig Pillars
If you’ve searched for or stumbled across this page then you probably already know what an OS Trig Pillar is. If you don’t then this article from the Ordnance Survey is a good place to start.
There were 30 OS Trig Pillars built in Greater London of which 24 are still in place. Of these some are on private land and are visible from a distance but not reachable. There’s a further 14 Trig Pillars that are outside of Greater London but inside of the M25. Special mention goes to TP9117 North Ockenden which is inside Greater London but outside of the M25.
I completed my mission to to visit all accessible and visible Trig Pillars within Greater London and the M25. The definition of accessible is somewhat subjective though as some that I’ve listed as accessible are just off the public right of way. Looking at the logs, there’s others who have successfully bagged ones I’ve listed as inaccessible but I’ve taken a more risk-averse approach and avoided trespassing, causing damage or scaring animals. Always check the logs on Trigpointing.uk to see how easy it is to access a pillar.
