Despite his extreme brutality, Moulay Ismail is highly revered by Moroccans themselves. So much, that his mausoluem is ranked as an Islamic sight. Although only parts of it are open to non-Muslims, it is the only one in Morocco that accepts this category of visitors. The parts that anyone can enter are fortunately highly rewarding esthetically. Ethics may be different issue, although helped by the long time passing; the thousands of people died from the brutal hand of the regime of Moulay Ismail simply for being non-Muslims.
Being a shrine, local women frequent the place seeking good blessings, baraka by touching predefined spots.
Admission is free, open every day except Friday (then open for Muslims), 8.30-12.00 and 14-18.00.
