Big Hole.
The Big Hole is a staggering physical record of the 19th-century diamond rush, recognized as the largest hand-dug excavation on earth. Between 1871 and 1914, roughly 50,000 miners used little more than picks and shovels to remove 22 million tons of earth, leaving behind a crater that plunges over 200 meters deep. Today, a cantilevered steel platform allows visitors to lean out over the massive precipice to view the turquoise water at the bottom. The surrounding site functions as a living history museum, featuring a recreated townscape of vintage buildings, original mining gear, and the Diamond Hall, which houses a massive collection of rough stones. It is a stark, impressive monument to human labor and the industrial obsession that effectively built modern Kimberley.
