Sula Sgeir is a small, uninhabited Scottish islet in the North Atlantic, 18 kilometres (9+1⁄2 nautical miles) west of Rona. One of the most remote islands of the British Isles, it lies approximately forty nautical miles (seventy kilometres) north of Lewis and is best known for its population of gannets. It has a narrow elongated shape running north-northeast to south-southwest, and is approximately 900 m long by typically 100 m wide (apart from a central headland projecting a further 100 m on the easterly side).[4]
A ruined stone bothy called Taigh Beannaichte (Blessed House) can be found on the east headland, Sgeir an Teampaill. A small automated lighthouse on the south end at Sròn na Lice is regularly damaged by the huge waves which break over the island during rough North Atlantic storms. Despite this, the island has diverse flora.[citation needed]
