Tanneries (or a district of dyers) is situated in Morocco and it is famous for incredible leather goods. Men work the leather in the tanning and special dying vats, they use the same technique as was used centuries before. The smell is very strong and once smelled it you will never forget it.
Just imagine, each of these vats is nearly 1 meter across, they are full of various paints and oil tanning liquors. You will get an opportunity to view everything from a tall building on a hillside. I perfectly understand how difficult it is, but… so amazing. But, after this excursion I think most people will have some troubles while wearing their usual leather jackets.
