Bou Inania Madrasa, built in the 14th century under Marinid Sultan Abu Inan Faris, is a masterpiece of Moroccan architecture. It features intricate wood and stucco carvings, stunning zellige mosaics, and a central courtyard with marble fountain. It is the only madrasa in Fes with a minaret and active mosque. The ornate wooden doors and carved cedar ceilings showcase the pinnacle of Marinid craftsmanship. Student rooms on the upper floor overlook the courtyard.
