Fresh, modern breeze comes from the heart of the holly Islamic City, as the Makkah Royal Clock Tower embodies the prototype of contemporary skyscrapers and architecture. The tower was constructed as a part of the King Abdulaziz Endowment Project, and offers luxurious accommodations for those Muslims, who visit the city during the Hajj period. As lots of devout Muslims worship five times a daily period, there are innovative elevator solutions, with which an incredible number of 75,000 people can exit all seven buildings at the same time. The tower is supplied with 96 elevators that can move at a speed of 6 m/s!
