The Kwame Nkrumah Presidential Library was born from the dream of Samia Nkrumah, the daughter of the political leader Kwame Nkrumah who led Ghana to independence in 1957. She is now leading the political movement of the father Convention People 's Party. The library is designed as a large square of knowledge: a catalyst tool for society and a privileged engine for social innovation. There are spaces for reading and consultation but also spaces of meeting and confrontation. There are spaces for events and conferences, workshops and activities of co-working, workshops for music and visual arts and crafts. The library will become part of the network of the Ghanaian education system being one of key tool for the training of new generations. The project is localized to Akosombo, near Lake Volta , the largest artificial lake in the world, a source of drinking water and fishing site where live more than 2 million Ghanaians. Finally, the Kwame Nkrumah's Presidential Library is a bioclimatic building able to maintain high levels of thermal, visual and audible comfort throughout the whole year, thanks to the balance of a few elements: shape, materials and simple technologies.
