Abraj Al Bait

Situated adjacent to the Great Mosque in Mecca, Saudi Arabia, the Abraj Al Bait complex is a government-owned development of seven skyscraper hotels designed to host religious pilgrims. Built between 2004 and 2012 by the Saudi Binladin Group at a cost of 16.00 billion dollars, the megastructure encompasses 1,575,815 square meters of built floor area, ranking among the largest single-building floor plates on Earth. The central tower, known as the Makkah Clock Royal Tower, reaches an architectural height of 601 meters across 120 floors. It features the world's largest clock faces, measuring 43 meters in diameter and illuminated by two million LED fixtures visible up to 25 kilometers away. Designed by German engineering firm SL Rasch and Dar Al-Handasah, the complex incorporates a 10,000-person prayer hall, a five-story shopping mall, residential apartments, and twin helipads. Its construction required excavating the historic Ajyad Fortress and managing massive logistics in Mecca's dense urban center.
