Fes tannery

The powerful smell emanating from some of these ancient tanneries is quite overwhelming. A part of the process of turning the animal hides (camel, goat, sheep, cow) into leather involves marinating them in pigeon poo for a few weeks. Given these tanneries have been around since the 13th century, a slight pong is understandable. Fortunately our guide, who not surprisingly was also a leather goods salesman, gave us each a handful of fresh mint to cover the smell.
