The Bab Doukkala Mosque, built by a sister of the Saadian sultan Mohammed al-Sheikh in 1557–8, is one of the finest 16th-century mosques in Marrakesh. Its minaret — tall, elegant, decorated with geometric zellige tile panels — is visible across the rooftops of the northwestern medina and is one of the landmarks used for orientation by those walking in the less touristed northern quarters.
The mosque is active and closed to non-Muslims, but the exterior is worth examining closely: the minaret proportions, the carved stucco around the entrance arch, and the relationship between the mosque and the urban fabric around it demonstrate the sophistication of Saadian architectural patronage outside the royal Kasbah. A small fountain in the square provides ritual ablution water and is itself decorated with careful tilework.
