Located in the Fort campus of the Mumbai university, the tower was modelled on Big Ben and designed by Sir George Gilbert Scott. Previously called the Library Tower, the name was later changed to honour Jennie McGraw, who donated the chimes, and her father, trustee John McGraw.

Situated in the central campus of Cornell university in Ithaca, New York, the Cornell chimes - a 21-bell chime in the McGraw Tower - first rang at the university's opening ceremony in 1868. According to the Saudi Ministry of Religious Endowments, the project, including the five-storey mall, residential towers with two heliports and a conference centre, cost $15 billion.

The clock itself is the world's largest clock face and the building is metres from Islam's most sacred site, Masjid al-Haram. Also known as the Makkah Royal Clock Tower Hotel, the clock tower is at the pinnacle of the fourth largest free-standing structure in the world.
