Fes el-Bali is the largest car-free urban area in the world and one of the most well-preserved medieval cities on Earth. Founded in the 9th century, this UNESCO World Heritage Site is a labyrinth of over 9,000 narrow alleys, bustling souks, ancient mosques, and hidden riads.

The medina is home to the University of al-Qarawiyyin, founded in 859 AD and recognized as the oldest continuously operating educational institution in the world. The famous Chouara Tannery, with its colorful leather-dyeing pits, is one of the most photographed sights in Morocco.

Pro tip: Hire a local guide for your first visit. The medina is genuinely labyrinthine, and a knowledgeable guide will help you discover hidden gems and navigate the complex network of alleyways.
