In Morocco by Edith Wharton — Read

Outside the sacred precincts of Moulay Idriss and Kairouiyin, on the other side of the Oued Fez, lies El Andalous, the mosque which the Andalusian Moors built when they settled in Fez in the ninth century.

It stands apart from the bazaars, on higher ground, and though it is not _horm_ we found it less easy to see than the more famous mosques, since the Christian loiterer in its doorways is more quickly noticed. The Fazi are not yet used to seeing unbelievers near their sacred places. It is only in the tumult and confusion of the _souks_ that one can linger on the edge of the inner mysteries without becoming aware of attracting sullen looks, and my only impression of El Andalous is of a magnificent Almohad door and the rich blur of an interior in which there was no time to single out the details.
