The museum houses vast treasures in buildings on the third court. Sometimes the material is expensive, but the result is ugly. Now as so often taking pictures is forbidden. After a restoration I also found the display in general was more geared to effect than to proper inspection, with spotlights all over. Here are some pictures I took (as slides) during a visit when pictures could be taken.
In 2016 even visiting was impossible, I think restorations were in progress, some necessitated by recently come to light structural problems.

There elsewhere is an area where religious treasures are housed, so you can see the staff of Moses if you believe it to be genuine, and similar artifacts. Taking pictures there: forget it.
