What makes Robben Island historically important?
Lying seven kilometres off Cape Town's coast in Table Bay, Robben Island served as a maximum-security prison for nearly four centuries — most infamously during apartheid, when political prisoners including Nelson Mandela, Walter Sisulu, and Ahmed Kathrada were held here. Since 1999 it has been a UNESCO World Heritage Site and a living museum. Tours are led by former political prisoners who walk visitors through the bleak cellblocks, the lime quarry where Mandela laboured, and the tiny cell — barely two metres by two-and-a-half — where he spent 18 of his 27 years of incarceration.
