The Iziko Slave Lodge is Cape Town's oldest surviving colonial building. It went up in 1679, after fire destroyed its predecessor. It has stood at the top of Adderley Street ever since.

Constructed by enslaved people, it housed over a thousand men, women and children at its peak, crammed into a space designed for six hundred. No windows. Preventing escape was the point.

The lodge also served as the city's main brothel. When Dutch commissioner Van der Reede visited in 1685, he found children throughout the building and had only to glance at them to see how many had white fathers. It later became the Supreme Court before conversion to a museum.

VoiceMap's tours use the lodge to trace the full arc of Cape slavery: from the first ships arriving in 1658, through individual lives and family histories, to the midnight ringing of the Groote Kerk bell on 30 November 1838, marking slavery's end.
