Do non-Muslim women need to cover up at Hassan II Mosque?

Yes, at the Hassan II Mosque in Casablanca — one of the few mosques in Morocco non-Muslims can enter — women (and men) should dress modestly, meaning shoulders and knees covered, though a head covering is not required. It’s an active place of worship visited on a guided tour, so respectful dress is expected of everyone.

Practically, that means long trousers or a maxi skirt and a top that covers the shoulders; a scarf over the hair is optional and appreciated but not mandatory for the mosque tour. You’ll remove your shoes before entering, so easy footwear helps.

If you turn up under-dressed you may be refused entry to the tour, so it’s worth planning your outfit around the visit. The same modest standard is a safe default for any religious site or shrine in the country.
