The courtyard is perhaps the most impressive part of the building. This area used to be open-air, but now the courtyard is covered. The original courtyard however is preserved, including the tiles and the designs.
There are plenty of things to see here, especially if you are interested in modern art. I did enjoy the exhibits, but I actually enjoyed the architecture the most, as that seems to be the pattern of my experience in Morocco. I spent an hour or so in here, wandering and wondering in the midst of the pillars, checking out the amazing design and architecture.
Pay it a visit if you can.
