The Cullinan Diamond Mine is renowned as a source of large, high-quality gem diamonds, including Type II stones, as well as being the world’s most important source of very rare blue diamonds. Cullinan earned its place in history with the discovery of the Cullinan diamond in 1905, the largest rough gem diamond ever found at 3,106 carats, which was cut to form the two most important diamonds in the British Crown Jewels.
Fort Klapperkop was the third fort erected before the outbreak of the Anglo-Boer War (1899–1902) to protect Pretoria. It has been restored with historical accuracy and arranged as a museum, with permanent exhibitions of Anglo-Boer War objects and furniture. The fort has the following rooms: Ammunitie, Hospitaal, Keuken, Machine, Telegraaf, Stal and Manschappen.
