The most remote inhabited island on Earth
A volcanic speck in the South Atlantic roughly 2,400 km from the nearest land, home to fewer than 250 people sharing just eight surnames — and reachable only by a six-day boat journey, since there is no airport.
Settled permanently in the early 1800s after a garrison was stationed there during Napoleon's exile on St Helena, Tristan da Cunha became a British colony soon after and has remained one ever since. A 1961 volcanic eruption forced a full evacuation to England — most islanders chose to return two years later rather than stay.
