This is one of the gates to enter the old fortified town of Tiznit.
Besides this door (bab means door) there is a karge muslim cemetery with a very important white "Marabou's" tomb.
From here you can easily get to Source bleu, a place dedicated to the town patroness Lalla Tiznit, which tells the story that she was a prostitue that turn into a saint or sacred person. the place is not very clean nowadays, but people said that after she died and became a martir here, water started to come out of the spot where she actually died.
many restaurants from where you can choose on the new part of town. also many street cafes where you can enjoy nice mint tea.
On the area of Mechouar you have also many cafes and street vendors with food. you can get tajine in many places and you can actually choose your pick just by walking and looking people cooking tajines on the front part of their restaurants. also a lot of grilled meat.
