Be invited to a traditional Hungarian dance by a friendly robot, watch a robotic dog perform silly tricks (and have it face-identify you) or learn about how robots have been making life better for Japan's children and senior citizens at medical institutions and retirement homes at Robosquare, a mix of store and exhibition space for all things robotic.

You will be surprised by the straight layout of the city's historical heart in sharp contrast to the usual maze of streets. A walk through Rabat's medina could look like this: start your visit at the Bab El Had gate and take Souika Street, the largest and probably busiest street in the medina. You will arrive in the Es Sabat souk, the shoe market, covered with reed mats and overflowing with babouches (leather slippers) as well as silver and gold jewellery. You then come to the partially glass-roofed Rue des Consuls where craftsmen make woollen carpets, fabrics and copperware. The medina also offers low-priced and local food, so do not hesitate to try mint tea, pastillas or tagine.
