Princess Nora Bint Abdul Rahman University opened in 2011 just north of Riyadh. This change in land use is noticeable between King Khalid International Airport and the residential areas of Riyadh. The college sits along the highway that curves along the campus. With a capacity of 40,000 students, it is the largest women-only university in the world. The $5.3 billion (US) campus covers over 8 million square meters.
