Summary
| DescriptionBarn Hill Triangulation Pillar - geograph.org.uk - 476193.jpg |
English: Barn Hill Triangulation Pillar Distant lines of sight for surveyors would not have been good from this pillar. This is the——best aspect although the "BT Tower is also just visible in an ESE direction." The view——to the north. And west is totally blocked by, "trees." The new Wembley Stadium arch is just visible through the murk. This is possibly the closest OS Triangulation Pillar——to central London. |
