Possibly the only white building in the Pink City?

A striking thing about Marrakesh is the uniform colour of which all buildings are made up of - a rose/pink shade. We were told that anyone who dared to put up a building that did not have this earthy shade would inevitably wake up the next day and find it had been painted pink for them...for free! So I was very amused to see this religious building which was obviously exempt from the rule!
