In the heart of Fes el-Bali, just past the blue Bab Bou Jeloud gate, sits a 14th-century building that breaks the rules of every other madrasa in Morocco. Bou Inania Madrasa, commissioned in 1350 by the Marinid sultan Abu Inan Faris and finished five years later, is the only such institution in the country authorised to hold Friday congregational prayer — a privilege normally reserved for full mosques.

Visitors enter through a modest doorway off Talaa Kebira to find a marble-paved courtyard fed by the underground Oued Fes, every surface either carved cedar, sculpted stucco or green-and-white zellij. The site spreads across roughly 1,500 m² and two floors, with student cells lining the upper level and classroom chambers framing the courtyard. A square minaret rises above the complex.

For non-Muslim travellers, Bou Inania is rare access to a working historic religious building — entry runs around 20 MAD, and the site is part of the UNESCO-inscribed Medina of Fes (1981). The prayer hall closes briefly five times a day for prayer; otherwise the madrasa is open roughly 09:00 to 18:00.
