After visiting Sammy Marks’ Museum, head north to historic Cullinan, a pretty 100-year-old village full of quaint Herbert Baker architecture. It is best explored on a sluggish, Sunday afternoon stroll. The village is home to Cullinan Diamond Mine, one of the biggest and most productive diamond-bearing kimberlite pipes in the world. It has produced three of the largest diamonds ever found. The largest, the 3106-carat Cullinan, as it was called, was 11cm by 6cm in rough form and was presented to King Edward VII. You can don a tin hat and organise a tour of the mine through Premier Diamond Tours.
To get here, take the N4 east and the Hans Strijdom off-ramp, then turn left and follow the signs.
