Jan Filip It is really small. There are no English descriptions - and that's a pity. It's worth a visit just for the beautiful garden and the nice view from the tower. However, you can have such (and nicer) views for free elsewhere. I think the entrance fee is 100 MAD.
GoGo Guide Great place for quick history lesson. Not a lot of information but the location is in the Medina which makes it a good place to start
Zelia vitorino Place is not very interesting, you can see it from the door. Price is 10Dh for moroccans and 70Dh for foreigners. Someone who pays the 70 are silly because is not worth it. If they would charge 20Dh or 30 Dh for foreigners they would have much more money because people would pay, but 70 is just abuse.
Kiril Kardzhaliyski Not very interesting place. Entrance fee is high for tourists. The only thing that is interesting is the tower that you can climb and make pictures
Iulia Prundurel The entrance is 60 Dh but there is nothing to see inside. The museum part is made up of 2-3 pictures and pots. You can go in on of the towers to get a view of the city but you can do the same from one of the many cafes or hostels with a rooftop terrace. The is extremely overprices.
