SITE VISIT

In April 2003 the pillar sustained a vandal attack. It was repaired by Historic Scotland on behalf of the Ordnance Survey in June 2003. The pillar was reconstructed with a wider cross section to the lower half of the trunk, and a ledge is provided at mid height to accommodate climbing without excessive scuffing to the vertical faces. Spider centre open but filled with debris. Flush bracket faces southwest. All sighting holes plugged. Extinct volcano, Arthur’s Seat is Edinburgh’s highest inner city summit at 823 Ft, 251m. This summit, like Blackford Hill and Calton Hill is always very busy. Arthur’s Seat is part of Holyrood Park which is crown property and always open to the public. The most popular route to the summit is from Dunsapie Loch via the east slope. There are other routes from the southwest for walkers which the desire for more of a climb. There is a 360° panoramic view from Arthur’s Seat. Over thirty other trigged landmarks can be spotted from here. There is a view indicator at the summit. The pillar is perched on the highest rock.
