The entrance vestibule of the Hassan II Mosque in Casablanca acts as a transitional space before entering the main prayer hall. Open to the outside, it allows visitors to take in the grandeur of the mosque’s exterior while offering a sense of anticipation. The area is framed by large stone columns and features beautiful tilework, which is characteristic of Moroccan architecture. This open-air entryway leads to a set of stairs that guide visitors into the mosque’s interior. The space is designed to reflect the traditional Moroccan aesthetic, with detailed geometric patterns decorating the floors and walls. It serves not only as a functional passage but also as an architectural statement that introduces visitors to the grandeur and intricacy of the mosque’s design.
