Chouara Tannery is one of three extant tanneries in Fès.
The smell was nearly unbearable at first, since it’s a mixture of cow urine, pigeon dung, quicklime, water, and salt.
We basically had to bribe the tannery guide (MAD15, or US$1.50) to let us out.
These guys are working with their legs to be certain the leather is in the dye.
