The Clock Towers
Government-owned hotel complex with the world's tallest clock tower.
The Clock Towers (Arabic: أبراج الساعة, formerly Abraj al-Bait) is a government-owned complex of seven skyscraper hotels in Mecca, Saudi Arabia. It is part of the King Abdulaziz Endowment Project, designed to modernize the city for pilgrims. The central tower, the Mecca Royal Clock Tower, is the fourth-tallest building and sixth-tallest freestanding structure globally. Guinness World Records recognizes it as the tallest clock tower in the world, and the entire seven-building complex ranks as the second most expensive building ever constructed.
The complex sits 300 meters from the Great Mosque of Mecca, Islam’s most sacred site. Built by the Saudi Binladin Group, the project cost US$15 billion. Its construction required demolishing the Ajyad Fortress, an 18th-century Ottoman citadel, in 2002—a move that sparked outcry, particularly from Turkey. The tallest tower reaches 601 meters, making it Saudi Arabia’s tallest building. It houses a five-star Fairmont hotel and a five-story shopping mall with parking for over a thousand vehicles.
The clock faces, one on each side of the main tower, are the world’s largest at 43 meters square. The clock itself is the highest architectural clock globally, with its roof 450 meters above ground. Behind the faces lies an astronomy exhibition, and the spire base contains a scientific center for moon sighting and an atomic clock controlling the tower’s time. The clock is visible from 25 kilometers away, illuminated by 2 million LED lights, with Arabic script reading "God is greatest" or "There is no god but Allah. Muhammad is the messenger of God." The minute hand is 23 meters long, the hour hand 18 meters. The clock runs on Arabia Standard Time, not Mecca Time.
The spire includes an eight-story glass-covered base called The Jewel, housing a scientific center, a small exhibition, and an observation deck at 484 meters. The highest floor was intended for air traffic control over Mecca, though this was not implemented. Non-Muslim construction workers were barred from the site; some Polish and German specialists converted to Islam to gain access. The façade was built by Premiere Composite Technologies, and the clock by German firm PERROT GmbH & Co. KG. Originally planned at 734 meters in 2006, the final height was reduced to 601 meters by 2009.

Lore & Background
The Clock Towers complex was built after the demolition of the Ajyad Fortress, an 18th-century Ottoman citadel on a hill overlooking the Grand Mosque. It contains a five-star hotel operated by Fairmont Hotels and Resorts, a five-story shopping mall, and a parking garage for over a thousand vehicles. The clock faces on all four sides are the largest in the world, illuminated by 2 million LED lights, and the clock is set to Arabia Standard Time (UTC+03:00). No injuries or deaths were reported in either incident. Non-Muslim members of the construction team were not allowed to visit the site, and some specialists from Poland and Germany converted to Islam to be able to do so.
Reader's Guide
The Clock Towers represent a major modernization effort for Mecca, aimed at accommodating the millions of pilgrims who travel annually for the Hajj. As the world's second most expensive building complex, it symbolizes the Saudi government's investment in religious tourism and infrastructure. The complex's location on the site of the demolished Ajyad Fortress has been a source of controversy, drawing criticism from Turkey and heritage advocates for the loss of an 18th-century Ottoman citadel. The clock tower's attempt to promote Mecca Time as a global standard, though ultimately set to Arabia Standard Time, reflects the complex's role in asserting Islamic identity on a world stage. The towers' massive scale—including the largest clock faces in the world and a spire with a crescent weighing 35 tonnes—makes them a landmark visible from 25 kilometers away. The complex's construction by the Saudi Binladin Group, the Kingdom's largest construction company, underscores the intersection of state power, religion, and commerce in contemporary Saudi Arabia.
