The Fes tannery is the oldest one in the world. It has more than 9 centuries of history.
The tannery is composed of numerous stone vessels filled with a vast range of dyes and various odorous liquids. The tannery processes the hides (skins) of sheep and goats, turning them into high quality leather products such as bags, coats, shoes, slippers and other similar products. This is all achieved manually, without the need for modern machinery. Men work in unbearably hot conditions (in the summer - 40 degrees and above). The tannery is a good example of mass production, a process that we often consider as being modern.
