The Chouara Tannery which is surrounded by shops. To look into the tannery you need to visit one of the shops - with no commitment to purchase, however, you will be shown many products from handbags, to clothing to poufs. You are given mint sprigs to hold near your nose as the smell from the tannery is a bit overwhelming.
The tannery is broken into two areas - the softening (the white vats) and the dyeing vats.
