Hassan Fathy
The mausoleum sits atop a hill along the west bank of the Nile, where it overlooks Aga Khan III and Begum Om Habibeh Aga Khan's villa, the Prince Sadruddin Aga Khan House. The villa was designed by Egyptian architect Hassan Fathy, and it served as a winter home for Aga Khan III, whose will stated that he would be buried near the villa two years after his death.
