<p>The Orkneys, a group of almost 70 islands and islets, lay about eight miles off the eastern end of the northern coast of the Scottish mainland, separated from Caithness by the Pentland Firth. There were three main groups of islands: the South Isles, which included Hoy and South Ronaldsay; Pomona, or the Mainland, on which was situated the capital Kirkwall, a royal burgh; and the North Isles of Shapinsay, Eday, Stronsay, Sandray, Westray and North Ronaldsay, among others. Stromness, which was also on the Mainland, was a burgh of barony.
