This thematically arranged book displays the full range of the Aga Khan's patronage of architecture. The Aga Khan is one of the most ardent patrons of architecture and historic preservation in the world. Since inheriting his title as spiritual leader of the Shia Imami Ismaili Muslims, usually known as Ismailis, fifty years ago, he has fostered and commissioned numerous structures and restored a multitude of buildings from North America to East Africa. The prestigious Aga Khan Award for Architecture, first given in 1980, recognizes projects that benefit the Muslim world for their excellence in contemporary design, community improvement and development, restoration, re-use, and area conservation. For the first time, this book presents projects from universities and historic restoration programs that bear the Aga Khan's name to religious centers, museums, and development efforts in more than twenty countries. Through the Aga Khan Development Network, the Aga Khan occupies a unique place in the world of architecture and this book reveals the range and breadth of his activities.
