Gold Reef City Theme Park

This guide to Gold Reef City in Johannesburg descends into a former gold-mine shaft, once the richest on the Witwatersrand reef, alongside the tens of thousands of miners who worked it and the donkeys hauled down for months at a stretch. You'll hear how workers from dozens of backgrounds built Fanagalo, a stripped-down language just for keeping a crew alive underground, and how deep the shaft's tunnels eventually reached. A listening tip: it's best heard on the cage ride down to level five.
