evidence: Rockall (/ˈrɒkɔːl/) is an uninhabitable granite islet in the North Atlantic Ocean. The United Kingdom claims that Rockall lies within its territorial sea[1] and is part of its territory, but this claim is not recognised by Ireland.[2][3] 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. [...] Irish claims to Rockall are based on its proximity to the Irish mainland;[81] however, the country has never formally claimed sovereignty over the rock. Although Rockall is closer to the UK coast than to the Irish coast,[4][5] Ireland does not recognise the UK's territorial claim to Rockall, "which would be the basis for a claim to a 12-mile territorial sea".[9][82] [...] The United Kingdom of Great Britain and Northern Ireland claims Rockall along with a 12-nautical-mile-radius (22 km) territorial sea around the islet inside the country's exclusive economic zone (EEZ).[1] The UK also claims "a circle of UK sovereign airspace over the islet of Rockall".[1]
