Arthur’s Seat, an ancient volcano, is the main peak of a group of hills in Edinburgh sitting 823 feet (251 metres) above sea level. This plan was engraved at The Ordnance Survey Map Office, Southampton, in 1856 and depicts the hills surrounded by the city. A climb to the top rewards walkers with excellent panoramic views of Edinburgh and beyond. One popular path is known as the Radical Road after it was paved in the aftermath of the Radical Rising of 1820, using the labour of unemployed weavers from the west of Scotland to provide work relief.
