The architect Gerard Moerdijk, called this hall in which the frieze was placed, the Hall of Heroes. A historic frieze (92 m x 2.3 m), which consists of 27 wall panels, was mounted against the walls. It depicts important events from the Great Trek. The frieze was designed by four South African sculptors: Hennie Potgieter, Peter Kirchhoff, Frikkie Kruger and Laurika Postma. The plaster models were shipped to Italy where it was sculpted from Italian Quercetta marble, by 40 Italian chisellers and 6 Italian sculptors. The completed frieze weighs approximately 200 tons.
