Johannesburg, South Africa, 19 December, 2018. An installation about prayer is seen at a block of isolation cells at the Old Fort on Constitution Hill. 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. Prison guards and soldiers also feature in the exhibition as the Old Fort was a military garrison during the Anglo-Boer War. Today, the Fort is a museum. Credit: Eva-Lotta Jansson/Alamy Live News
