Edinburgh is the capital city of Scotland and one of its 32 council areas. Located in the south-east of Scotland, it is bounded to the north by the Firth of Forth estuary and to the south by the Pentland Hills. With a population of 506,520 in mid-2020, Edinburgh is the second-largest city in Scotland by population and the seventh largest in the United Kingdom. The royal burgh of Edinburgh was founded by King David I in the early 12th century on land belonging to the Crown, and has been capital of Scotland since at least the 15th century. This aerial photograph, with Edinburgh Castle in the foreground, was taken around 1920.Photograph credit: Alfred Buckham; restored by Adam Cuerden
