The oldest university in the world isn’t Oxford or the Sorbonne—it’s the University of Al-Karaouine, and you’ll find it in Fez el Bali. This walled city, a UNESCO World Heritage Site, will transport you back to medieval times. Visit the ancient maze-like quarters of the Medina to Fez el-Bali and the four imposing Gates of Fez, with their distinctive Moroccan tile work.
