It was the largest building in Saudi Arabia between 2000 and 2002 and currently is the seventh tallest building in the country, after Kingdom Centre, Burj Rafal and Abraj Al Bait. The tower is named after King Faisal bin Abdulaziz, and at some date ranked as the 325th tallest building in the world.
