Kimberley (Northern Cape)

Kimberley is the capital of the Northern Cape Province of South Africa. Amongst other things, it is famous for its Big Hole, the world's largest hand-dug excavation that was created when thousands of people searched for diamonds at the end of the 19th and the beginning of the 20th centuries. By 14 August 1914, 22.7 billion kg of rock had been excavated, yielding 2722 kg of diamonds.
