The huge convertible umbrellas at the Prophet's Holy Mosque were designed in an accurate architectural way, with each one on top on the other. The height of the first umbrella is 14.40 meters and the other 15.30 meters. The height of the umbrella when folded will reach 21.70 meters. A total of 250 umbrellas were installed at the courtyards of the Prophet's Holy Mosque. They were installed in two phases: the first phased included 182 umbrellas and the remaining 68 were erected in the second phase. The total area shaded by the the umbrellas stands at 143,000 square meters with the total number of worshippers under the umbrellas reaching around 228,000 people. The umbrellas contain 436 spray fans that were installed at the sides of the umbrellas. Each fan has 16 openings that sprays water, with the fans treating around 200 liters of water per hour. Umbrellas are provided with water through two stations that purify spray water. The fans moisturize the external air so the guests of the Prophet's Mosque enjoy proper atmospheres. All these procedures are carried out from a main control room that monitor and maintain the umbrellas. — SPA
