Cape Town is now home to one of the world's largest collection of bronze statues - the March for Freedom exhibition in Century City, which showcases well-known figures in South African history. The life-sized collection features bronze statues of former president Nelson Mandela, struggle icon Winnie Madikizela-Mandela, Zulu king Shaka Zulu and sportsman Basil d'Oliveira. CEO of the exhibition, Dali Tambo, says the project is a promise to his father Oliver Tambo. "I told him while visiting his grave that there weren't any statues of him in South Africa. I promised him that I [would] make one of him," he said.Later that night he says he heard his father tell him that there shouldn't just be a statue of him, but of all who served and shaped the country.He and 40 other artists worked tirelessly to put the exhibition together. He wanted to tell South Africa's history through statues of key figures. "We are going to create a national treasure that encompasses our 350-year journey to liberation," he said."Many only resonate with the last generation, the Mandela generation, but it took so many other generations to secure our freedom. We represent a long march to democracy, from the 1600s to 1994."
