The area is declared a military museum. On 31 May 1979 the South African Defence Force Memorial was unveiled at Fort Klapperkop. It includes a statue of a soldier holding a R1 rifle, in memory of all members of the South African Defence Force who lost their lives serving their country.
Mussel is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval.
On each outside corner of the Monument there is a statue, respectively representing Piet Retief, Andries Pretorius, Hendrik Potgieter and an “unknown” leader (representative of all the other Voortrekker leaders). Each statue weighs approximately 6 tons.
