King Khalid International Airport is an international airport located about 35 kilometres (22 mi) north of Riyadh, Saudi Arabia, designed by the architectural firm HOK, and Arabian Bechtel Company Limited served as the construction manager on behalf of the Saudi government.

Riyadh is the capital and largest city of Saudi Arabia. It is also the capital of the Riyadh Province and the centre of the Riyadh Governorate. The current form of the metropolis emerged as an offshoot of the eponymous walled town following the dismantling of its defensive fortifications in the 1950s, after which the city underwent several phases of expansion and urbanization.
