A unique feature of the expansion project was the development of the twenty-seven main plazas. Each plaza is now capped by a state-of-the-art sliding dome, which can be rapidly opened or closed according to the weather and can be used in unison or separately as required. Elaborately carved stone friezes decorate the domes, and the plazas have been paved in decorative geometrically patterned marble tiles. The project also necessitated the building of six additional minarets, the most powerful visual sign of the Mosque, each 354-foot [105 m] construction crowned with a 4-ton gold-plated crescent.
The development of the surrounding open areas and the seven newly constructed entrances ensure the smooth passage of pilgrims into the Prophet’s Mosque. Indeed, the designers of the entire project have masterfully considered every eventuality of the existing and future capacity of the Mosque, and all this within the strictures of the existing architectural pattern. The building extensions have therefore been fitted out with a suitable number of staircases and escalators. The designers have added an extension to the roof area for praying purposes, whilst also allowing for the possibility of adding another floor to accommodate worshippers in the future.
