This book is a photographic journey on the origin and life of "Africa Hall" in Addis Ababa, Ethiopia - a building declared in 2015 "Monument to African History" and recently renovated - which was donated in 1961 by Emperor Haile Selassie to the United Nations. Africa Hall was designed by Arturo Mezzedimi, a young self-taught architect, to serve as the UN's continental headquarters and was the birthplace, in 1963, of the Organization of African Unity, now African Union.

The building came to life with an inspiring story of reconciliation at a crucial moment in African history, when the continent was emerging out of the colonial period and making headway into a new era of independence and envisaged unity. Through its architectural composition and the embedded artworks, it embodied a Pan-Africanist vision and its rising ideals.

Edited by the grandson of the architect and representing Italy's contribution to the renovation project, the book sits at the crossroads of photography, architecture, history, and art and comprises an amplitude of independent essays, contributions and recollections from authors of diverse profiles. Through impacting images and short articles, it addresses events of historical relevance on a global scale, for the entire continent of Africa, at a national level for Ethiopia, and locally for the city of Addis Ababa, concluding with an introduction to the life and work of its architect.
