The Historic Cities Programme (HCP) of the Aga Khan Trust for Culture (AKTC) promotes the conservation and re-use of buildings and public spaces in historic cities of the Muslim world. HCP undertakes the restoration and rehabilitation of historic structures and public spaces in ways that can spur social, economic and cultural development. Individual projects go beyond technical restoration to address the questions of the social and environmental context, adaptive reuse, institutional sustainability and training. In several countries, local Aga Khan Cultural Service companies have been formed to implement projects under the supervision of the HCSP headquarters in Geneva.
