Johannesburg, South Africa, 19 December, 2018. A silhouetted figure keeps guard over the Old Fort on Constitution Hill, as part of a new permanent exhibition there. Using technology such as holograms, the new exhibition additions officially opened in December, telling the stories about prisoners who were housed here, both during the gold rush and later during apartheid. During apartheid, The Old Fort housed white prisoners. Prison guards and soldiers also feature in the exhibition as the Old Fort was a military garrison during the Anglo-Boer War.
