Tristan da Cuhna is a small archipelago sometimes described as the most isolated in the world, as it is over 1500 miles away from the nearest landmass. It is situated in the Atlantic Ocean, has a population of around 300, and is a British Overseas Territory.
The capital is a strong contender for best-named capital in the world: Edinburgh of the Seven Seas, and the scenery and wildlife is pretty cool.
The islands were first occupied by the UK in the 1800s to prevent Napoleon from gaining a potential naval base. Interestingly, there was no currency on the island until the late 1940s. Until this time, the islanders would work for useful products and genuinely used potatoes as currency.
