Get lost in the compact and laid-back medina, with the many signposts. This is a largely residential and underrated medina and you won't be bothered - friendly kids will smile and most people passing by will greet you happily. Admire the beautiful houses typical of the region, built with sand and clay bricks, often with very intricate designs. Look out for a triangular shaped design - it is believed to bring good luck, and people once tossed coins onto the bricks making the patterns. Some of the roofs of the tunnels in the medina are made of palm wood - they are rather fibrous, and others, of apricot tree wood, which are normally used for richer families. Look out for the "jalousies" - dark apricot wood made peeping windows from the second floor where ladies used to sit. These allowed them to watch the people in the street without being watched, it being socially rare for ladies to be outside of the house much in the pass. The mosque doors are green and rounded whereas residences have are squared doors with beautiful nail designs - including jars (used to conserve palm products), Jewish stars and candles (for the substantial Jewish community that used to live here), and even bicycles (for locals who bike a lot). One of the houses belongs to a French family and you can see a "coq gaulois" perched on one of the house walls.
