The site of the complex is located across the piazza to the south from the main entrance (King Abdul-Aziz Gate) to the Masjid al Haram mosque, which houses the Kaaba. To accommodate worshippers visiting the Kaaba, the Abraj Al-Bait Towers has two large prayer rooms (one for men, one for women) capable of holding more than 10,000 people. The tallest tower in the complex also contains a five-star hotel, operated by Fairmont Hotels and Resorts, to help provide lodging for the millions of pilgrims that travel to Mecca annually to participate in the Hajj.
