An Overview of Abraj Al Bait
Located just meters from the Grand Mosque (Masjid al-Haram), the Abraj Al Bait complex was developed by the Saudi Binladin Group and commissioned by the Saudi government to modernize Mecca’s skyline and provide accommodations for millions of pilgrims.
- Height: 601 meters (1,972 feet)
- Completed: 2012
- Total Cost of Complex: Estimated at over $15 billion USD
The central Clock Tower is the fifth tallest freestanding structure in the world and features a rooftop space that includes the crescent structure and sophisticated maintenance systems.
Architectural Features of the Roof
The roof of the Clock Tower includes:
- The massive crescent moon structure, which alone weighs over 35 tons and is covered in gold-colored glass mosaic
- Lightning protection and wind resistance features for extreme elevation
- Access platforms and maintenance decks
- Advanced lighting systems used for religious and national observances
These elements make the roof not only structurally vital but also symbolically powerful, serving as a literal and figurative pinnacle of Islamic architecture.
Estimated Cost of the Roof
Due to its uniqueness and elevation, the cost of constructing the Abraj Al Bait roof—including the crescent structure—is estimated based on high-altitude construction and custom materials:
Estimated Metrics:
- Crescent Moon Structure Cost: Estimated between $90 million to $150 million USD
- Roof Deck Construction and Systems: Likely an additional $100 million to $200 million USD, given complexity and materials
Total Roof Cost Estimate:
Approximately $200 million to $350 million USD, placing it among the most expensive roof structures globally.
