Trig Points

Ordnance Survey triangulation pillars, built from 1936 onwards to re-survey Britain and made obsolete by GPS, the very thing that now finds them for you. Atlas tracks every standing pillar in the OS archive, over 6,000 of them, from busy summit pillars to forgotten ones in field corners and back gardens. The longest-running collectible in British walking.

6436 landmarks. Atlas tracks your progress against the full list automatically - no spreadsheet, no manual ticking.

How many of the 6436 have you done? Atlas already knows.

Atlas matches the GPS history you already have - Strava, GPX files, Apple Health, Health Connect - against every peak, trail and landmark in the UK. Nothing to record, nothing to plan; connect once and your lifetime record fills itself in.
