Constitution Hill is a historic site in Johannesburg that played a significant role in South Africa's journey towards democracy. It was once a prison complex where political activists, including Nelson Mandela, were held during the apartheid era. Today, it has been transformed into a museum and heritage site that explores the country's constitutional history. Visitors can take guided tours, visit the Old Fort prison, and learn about the struggles and triumphs of the South African people in their fight for freedom and equality.
