Magnificent Bou Inania Madrasa in Fez was founded by Merinid Sultan Abou Inan in the year 1351. The construction completed in 1358. Beyond the massive brass entrance doors, its interior courtyard is a masterpiece of elaborate zellige tilework from the 14th century. Today it is still an active religious building, and it is one of the few mosques in Morocco that remains open for all to visit, including those that are not Muslim, providing a unique experience for tourists.
