The Mosque of the Sharifs was the burial site of Idris II and evolved into the Zawiya of Moulay Idris II that exists today, while the al-Anouar Mosque has left only minor remnants.[3] The Qarawiyyin Mosque was first established as a place of worship but teaching lessons were also conducted within the mosque and it evolved to become a place for cultivating knowledge of the Islamic sciences and other sciences. Thus, it simultaneously developed into a major educational institution with scholarly status, and since 1963 it has been a state university of Morocco.[41][42][43]
