This is the Mausoleum of Aga Sultan Mohammed Shah the spiritual leader of the Ismailis, a Shi'ite sect based principally in India but with followers around the world. The Aga Khan III (1877-1959) chose Aswan for building his beautiful villa for its beauty and perfect winter climate, where he preferred to spend the winter and eventually he chose to be buried in Aswan as well.

His mausoleum is a very elegant pink granite structure of late 1950 origin, which also resembles the Fatimid tombs in Cairo. The Mausoleum has an excellent view, including Agha Khan's white villa below, and is near the Monastery of St. Simeons on the west bank at Aswan.
