The Full Story
Kiritimati, part of the Republic of Kiribati in the central Pacific Ocean, has the largest land area of any coral atoll, covering around 388 square kilometres. An atoll is a ring-shaped coral reef, island, or chain of islands that encircles a lagoon, formed as coral grows around a sinking volcanic island.

The atoll lies close to the equator and the international date line.
