Rockall located on terrain feature North Atlantic Ocean
Rockall () is an uninhabitable granite islet in the North Atlantic Ocean. The United Kingdom claims that Rockall lies within its territorial sea and is part of its territory, but this claim is not recognised by Ireland. It and the nearby skerries of Hasselwood Rock and Helen's Reef are the only emergent parts of the Rockall Plateau. The rock was formed by magmatism as part of the North Atlantic Igneous Province during the Paleogene.
Rockall's approximate distances from the closest islands in each direction are as follows: It is 301.3 kilometres (187.2 statute miles; 162.7 nautical miles) west of Soay, Scotland; 423.2 km (263.0 mi; 228.5 nmi) northwest of Tory Island, Ireland; and 700 kilometres (430 statute miles; 380 nautical miles) south of Iceland.
The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, 370 kilometres (230 mi; 200 nmi) to the east.The United Kingdom claimed Rockall in 1955 and incorporated it as a part of Scotland in 1972. The UK does not make a claim to an extended exclusive economic zone (EEZ) based on Rockall, as it has ratified the United Nations Convention on the Law of the Sea (UNCLOS), which says that "rocks which cannot sustain human habitation or economic life of their own shall have no exclusive economic zone or continental shelf". However, such features are entitled to a territorial sea extending 12 nautical miles (22 kilometres). Ireland's position is that Rockall does not even generate a 12-nautical-mile territorial sea for the United Kingdom owing to the UK's uncertain title to Rockall. Ireland does not recognise the UK's claim, although it has never sought to claim sovereignty of Rockall for itself. The consistent position of successive Irish governments has been that Rockall and similar rocks and skerries have no significance for establishing legal claims to mineral rights in the adjacent seabed or to fishing rights in the surrounding seas.
