The building is composed of three stacked, interlocking spaces: the
prominent entrance portal on the west side, the main space in the middle and
the semicircular mihrab (a niche which indicates the direction of Mecca) on the
southeast side. The three spaces are crowned with domes.Because the site available was 800 m2 and the programme of requirements
amounted to 2,600 m2, it was decided to organise the building vertically. The
mosque therefore counts four levels. The ground floor has mainly a
non-religious function.
The prayer halls for men are situated in the central square space
extending over the first and second floors with an internal balcony; on the
third floor there are prayer halls for women.
A library, the imam’s chamber, offices, classrooms and a guest room are
also accommodated on these levels. The prayer halls are interconnected by a
central well and natural light enters via the large, 25-metre-high central
dome, which is supported on four columns.
The Essalam Mosque is based on the so-called ‘Medina concept’ (on the
architecture of the Great Mosque in Medina) and in style builds on the
tradition of, inter alia, the 15th-century Mammeluke architecture found in
Cairo. The building is clad with slabs of coloured natural stone and has
accents in contrasting bluish grey stone.
