The tallest tower in the complex is the tallest building in Saudi Arabia, with a height of 581.1 metres (1,906 feet). Currently it is the fourth tallest freestanding structure in the world.
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. The project uses clock faces for each side of the hotel tower. The highest residential floor stands at 450 m (1,480 ft), just below the spires. The roof of the clocks is 530 m (1,740 ft) above the ground, making them the world's most elevated architectural clocks. A 71-metre-tall (233 ft) spire has been added on top of the clock giving it a total height of 601 m (1,972 ft). 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.
