This section of the database looks at the Ordnance Survey triangulation artifacts I have visited on my walks. I use the word 'artifacts' as the OS employed more than just pillars, and this list includes FBMs, Concrete Rings and some other types of trig point.
At the top of the page is a list of my most visited trig points, followed by trig points broken down by area and by hill group. I'm much closer to completing the trig point tables for the various English National Parks than I am for the different hill classifications.
I've now added a list of all the trig points I've visited over the years, along with an interactive map of their locations. This is probably of limited interest to anyone but me, but see what you think.Click for Trig Point Map
This is simply a list of the trig points I have visited most. I've avoided calling this my 'Favourite Trig Points' list, because although some of these are indeed firm favourites, this is not that list.

When I started bagging trig points I decided to group them by walking area (such as National Parks), as much to encourage me to find new routes as anything else. These are the trig points broken down by the areas that I walk in the most.
These are the trig points broken down by the different types. The traditional triangulation pillar is just one of a number of different types used by the Ordnance Survey over the years. Although I initially sought out all the different types, I now concentrate on what I call 'above ground' types, the one's you don't need to dig for!
