Abdallah al-Ghalib
During his reign, Abdallah al-Ghalib Billah resided in Marrakesh. He was a prolific builder who is responsible for building, among other projects, the Mouassin Mosque, a maristan (a hospital usually attached to a mosque), and the Ben Youssef Medrassa. He repaired and restored the originally Almohad-built Kasbah Mosque and he is also believed to have also begun the first mausoleum of the Saadian Tombs located behind that mosque.
