North Ronaldsay is the northernmost of the islands of Orkney and, with an area of 690 hectares (2.7 sq mi), is the fourteenth largest. Mentioned in the Orkneyinga saga, in modern times it is known for its historic lighthouse, migratory bird life and unusual breed of sheep.
North Ronaldsay lies around 4 kilometres (2.5 mi) north of its nearest neighbour, Sanday at grid reference HY759542. The island is around 5 kilometres (3.1 mi) long along its length and is defined by two large sandy bays; Linklet Bay on the eastern shoreline and South Bay at the south. The west of the island is very rocky with many skerries. Low-lying and exposed, the island's climate is extremely changeable and frequently inclement. The surrounding waters are stormy and treacherous, and have been a notorious "graveyard" for ships (hence the unusually early provision of a lighthouse on the island).
Hollandstoun at the south of the island is the most sizable settlement lying roughly equidistant from the airfield and the pier. The island is also home to a bird observatory.
The North Ronaldsay is a breed of sheep living on North Ronaldsay, the northernmost of the Orkney Islands, Scotland. They are one survivor of a type of sheep formerly found across the islands of Orkney and Shetland (the other is the Shetland), belonging to the Northern European short-tailed sheep group of breeds.
They are notable for living almost entirely on seaweed for several months of the year, except for a short lambing season – this is the only forage available to them, as they are confined to the shoreline by a 6 feet (1.8 m) tall dry-stone wall which encloses the whole island. The semi feral flock on North Ronaldsay is confined to the foreshore for most of the year to conserve the limited grazing inland. This breed is raised primarily for wool.
The Rare Breeds Survival Trust lists this breed as "vulnerable," with about 600 registered breeding females in the United Kingdom in Spring 2014.
Wool from the sheep is spun in Lanarkshire on the Scottish mainland and returned to Orkney for sale. However a small woollen mill now has a processing operation on North Ronaldsay. This mill processes the majority of Island-produced fleeces and supplies fibre for felters and spinners, as well as spinning yarn for knitters, many of whom live in Orkney producing fine clothing and other woollen goods for sale throughout Orkney.
