Inside the Glaoui (Glaoua) Palace.
A simply amazing place, and definitely worth trying to get a look inside - the mini-tour cost us 50dh (for two) and included a little bit of history, but mostly the leading around and opening of doors and pointing at things.
Evidently Abdou and his sister are the only two people that live there, have done so for several decades, and the place is (perhaps eternally) 'up for sale' for some figure touted to be around 6 million euros. An insane number of rooms and courtyards in the place, and each would take a breathtaking amount of time and money to properly restore.
The history of the place is well worth reading about too - http://www.vagobond.com/the-glaoui-glaoua-palace-in-fes-morocco/ is a good place to start.
