17 March - 6 June 2010. Described as the world's largest and most valuable collection of Islamic art, the Aga Khan's art collection goes on display for the first time in Germany. Comprising over 200 paintings, manuscripts, ceramics, and wood carvings, the treasures belong to the Aga Khan Trust for Culture and were specifically selected to represent a thousand years of Islamic art and history. Karim Aga Khan IV is the spiritual leader of the Ismaili Muslims and is regarded as a direct descendant of the Prophet Mohammed. From 2013 this collection will be permanently displayed in the new Aga Khan Museum in Toronto.
