The design of the Riyadh Airport Mosque is one of the most distinct landmarks in the airport by virtue of its Islamic architecture. It can accommodate 5,000 worshipers inside and another 5,000 in the plaza outside. Its location in the center of the passenger terminal establishes it as the most important structure on the airport and makes it the first sight visitors see as they leave the arrival area. The dome is 33 metres (108 ft) in diameter and towers 40 metres (130 ft) above the arrivals level roadway, higher than all of the other structures in the passenger complex with the exception of the control tower and minaret.
Passengers that go from one terminal to another at King Khalid Airport can use the moving sidewalks for transportation. The moving walkways are located in the three link buildings that connect the International and Domestic terminals.
