1Elliðaey Island House, Iceland
Tucked away on a tiny, uninhabited island in the Vestmannaeyjar archipelago, the Elliðaey Island House is often referred to as “the world’s loneliest house.” This small white structure sits on a grassy hill surrounded by sheer cliffs and the wild North Atlantic Ocean. The island is only accessible by boat, and its isolation has fueled numerous myths, including rumors of celebrity ownership.
