Salisbury Crags are a series of cliffs at the top of a subsidiary spur of Arthur's Seat which rise on the west of Holyrood Park. Below the foot of the cliffs is a large and steep talus slope falling to the floor of Holyrood Park with a track known as the Radical Road running in the space between the two. This track was given its name after it was paved in the aftermath of the Radical War of 1820, using the labour of unemployed weavers from the west of Scotland at the suggestion of Walter Scott.
