Muckle Flugga

From Freepedia

Muckle Flugga is a small rocky island north of Unst in the Shetland Islands. It is often described as the northernmost point of the British Isles, but the smaller, less interestingly-named islet of Out Stack is further north.

Muckle Flugga is home to a lighthouse, built by Thomas and David Stevenson in 1854, originally to protect ships during the Crimean War. The lighthouse was automated in 1995. Until then Muckle Flugga had been the northernmost inhabited point of the British Isles.
