Africa's amazing architecture: Do these buildings represent freedom?

The 1960s and '70s were revolutionary decades in terms of architecture, and some of the very best of it was built in Africa.
At least, that's how Manuel Herz sees it. An architect and historian, Herz has recently curated an exhibition on the subject for the Vitra Design Museum in Weil am Rhein, Germany. The exhibit, titled "Architecture of Independence: African Modernism" focuses on some of the most dynamic projects built in the wake of colonialism.
"Some of these buildings are really the most interesting and fascinating that were built in that era worldwide, but they have completely fallen off the radar," he laments.
Herz focused on a handful of countries: Senegal, the Ivory Coast, Zambia, Ghana and Kenya. Each building, he says, tells a story about that country's hopes and aspirations. Browse through the gallery above to see what those stories are.
