14. North Sentinel Island (Myanmar)
It’s surrounded by dangerous reefs, but North Sentinel is intimidating because of its inhabitants. The Sentinelese want nothing to do with the modern world and have repeatedly rebuffed attempts to make peaceful contact.
15. Rockall (Ireland)
Rockall is the tip of an extinct volcano reaching 20 meters (about 65 feet) above sea level, in seas with waves recorded as high as 29 meters (95 feet). In 1955, the British Empire, in its final territorial acquisition, seized Rockall, allegedly due to fears the Soviets would build a missile battery on it.
