I was prepared to see artefact about the islamic civilization from the prophecy of Mohamed PBUH. But the information was sporadic and organized by themes rather than dates. Nothing was from the past most artefacts are from 16th century upward. I liked the science and architeture exhibits and the meccah one.
Worth the visit but not the detour.
1 hour max unless you like to go through things with a fine tooth comb.
Btw. No guided tour was offered for us.
