One of the last synagogues, and right across from it, the large Jewish cemetery.
In the souks, step away from the main alleys near the square and don’t hesitate to explore the little side streets where no one goes. You’ll see lots of artisans there.
A really beautiful contemporary art museum: the MACCAL... Located within the Royal Golf grounds, you’ll need to take a taxi to get there. It’s a bit out of the way. Either keep the taxi or walk back on foot through an area full of wholesalers selling pottery of all sizes.
