The Imam ‘Ali Mosque is housed in a grand structure with a gold gilded dome and many precious objects in the walls. Nearby is the Wadi-us-Salaam cemetery, the largest in the world. It contains the tombs of several prophets and many of the devout from around the world aspire to be buried there, to be raised from the dead with Imām ‘Alī on Judgement Day. Over the centuries, numerous hospices, schools, libraries and convents were built around the shrine to make the city the center of Shīʻa learning and theology.
