The Royal Mile is a succession of streets forming the main thoroughfare of the Old Town of the city of Edinburgh in Scotland. The term was first used descriptively in W. M. Gilbert's Edinburgh in the Nineteenth Century (1901), describing the city "with its Castle and Palace and the royal mile between", and was further popularised as the title of a guidebook by R. T. Skinner published in 1920, "The Royal Mile (Edinburgh) Castle to Holyrood(house)". — Wikipedia
