This place is a little hard to get to but it's def worth a trip. When we went there was a really cool photography exhibit, although it wasn't part of the permanent collection. There are a lot of pieces made with recycled materials and/or garbage which are cool if you're into that type of art.
There's also a gorgeous outdoor area to sit and relax in, too. Very clean and quiet, a nice reprieve from the chaos of the Medina.
