The Big Hole, an awe-inspiring man-made crater is a gaping void, measuring 463 metres wide and 240 meters deep, was once the largest hand-dug excavation in the world, yielding an estimated 2,722 tons of diamonds between 1866 and 1914. The sheer scale of the hole, dug by over 50,000 laborers during its active years. Adjacent to the Big Hole lies the Kimberley Mine Museum, marking the initial discovery of diamond reserves in the country.
