Hassan II Mosque: What to Know Before You Visit

The Hassan II Mosque sits right on the Atlantic in Casablanca and is one of the very few religious sites in Morocco that welcomes non-Muslim visitors inside, which makes it a rare chance to see a working mosque's interior up close.

Can non-Muslims go inside

Yes — the Hassan II Mosque is one of the only functioning mosques in Morocco that allows non-Muslim visitors into the interior, and it does so through scheduled guided tours rather than open wandering. Most mosques across Morocco, including the historic ones in Fes and Marrakech, are closed to non-Muslims beyond the courtyards, so this is genuinely one of the few places in the country where you can see the inside of a mosque this size — the prayer hall, the retractable roof, the ablution area below — with a guide explaining what you're looking at as you go.

Visiting hours and how the tours run

Visits run as guided tours at set times through the day, several days a week, with tours paused during prayer times and on Fridays affected by midday prayer. Tours typically last under an hour and move through the main prayer hall, the ablution rooms beneath the building, and sometimes the exterior courtyard, with a guide giving the history and architectural details as you walk. Because tour times can shift around religious holidays and Friday prayers, we'd check locally or build in some flexibility on the day rather than planning right up against a tight schedule elsewhere in Casablanca.

What to wear

Modest dress is expected for everyone entering, which means covering shoulders and knees at minimum; women don't need to cover their hair, but a scarf on hand is a reasonable backup if you're unsure how a specific tour will handle it. Shoes come off before entering the prayer hall itself, so socks are worth having on rather than bare feet on marble. This is the same standard you'd want to follow at any religious site in Morocco, but it's enforced more consistently here since it's an active place of worship as well as a tourist stop.

Is it really one of the largest mosques in Africa

Yes, and the scale is part of why it's worth visiting even if you're not especially interested in architecture generally. It's one of the largest mosques on the African continent and has one of the tallest minarets in the world, and it was deliberately built on a promontory over the Atlantic so that part of its floor looks directly out over the ocean. Completed in the early 1990s, it's a modern building rather than a historic one, but the craftsmanship — zellige tilework, carved cedar, marble brought from across the country — is on the same level as Morocco's older monuments.
