Morocco is home to the world's oldest tanneries. Situated in the historic town of Fez, the Chouara Tannery dates back nearly a millennium. Despite this, the tanneries in the desert tours from fes still manufacture leather using traditional methods rather than utilizing modern techniques. According to other travelers who have been there and tour guides, many tourists go there to see if the tanneries smell. Because you have to pay a small fee to enter the tanneries, you can observe this historical exercise from the leather retailers that surround them.
