Makkah Royal Clock Tower Hotel

The Abraj Al-Bait Towers, also known as the Mecca Royal Hotel Clock Tower, is a building complex in Mecca, Saudi Arabia. The complex holds several world records, such as the tallest hotel in the world, the tallest clock tower in the world, the world's largest clock face, and the world's largest building floor area. The complex's hotel tower became the second tallest building in the world in 2011, surpassed only by Dubai's Burj Khalifa. The building complex is meters away from the world's largest mosque and Islam's most sacred site, the Masjid al Haram. The developer and contractor of the complex is the Saudi Binladin Group, the Kingdom's largest construction company.

The tallest tower in the complex stands as the tallest building in Saudi Arabia, and the tallest and largest hotel in the world, with a height of 601 meters (1,972 feet). It is the fourth tallest building under construction. Upon its official opening the structure would surpass Dubai International Airport having the largest floor area of any structure in the world with 1,500,000 m2 (16,150,000 sq ft) of floorspace. It also surpassed the Emirates Park Towers in Dubai as the world's tallest hotel.


The site of the complex is located across the street to the south from an entrance to the Masjid al Haram mosque, which houses the Kaaba. To accommodate worshipers visiting the Kaaba, the Abraj Al-Bait Towers has a large prayer room capable of holding more than 10,000 people. The tallest tower in the complex also contains a five-star hotel to help provide lodging for the millions of pilgrims that travel to Mecca annually to participate in Hajj.

In addition, the Abraj Al-Bait Towers has a five-story shopping mall (the Abraj Al Bait Mall) and a parking garage capable of holding over a thousand vehicles. Residential towers house permanent residents while two heliports and a conference center are to accommodate business travelers. In total, up to 100,000 people could be housed inside the towers. The project uses clock faces for each side of the hotel tower. The highest residential floor stands at 450 metres (1,480 feet), just below the clocks. The clock faces are 43 × 43 m (141 × 141 ft), the largest in the world. The roof of the clocks is 530 meters (1,740 feet) above the ground, making them the world's most elevated architectural clocks. A 71 metres (233 feet) tall spire has been added on top of the clock giving it a total height of 601 metres (1,972 feet), which makes it the second tallest building in the world, surpassing Taipei 101 in Taiwan. The tower also includes an Islamic Museum and a Lunar Observation Center which will also be used to sight the moon during the Holy Months.

Building was planned to be 485 meters tall in 2006. In 2009, it was published that the final height will be 601 meters. The complex was built by the Saudi Binladin Group, Saudi Arabia's largest construction company. The clock tower was designed by the German company Premiere Composite Technologies, and the clock by the Swiss engineering firm Straintec. According to the Saudi Ministry of Religious Endowments, the project cost $15 billion.
