The Kingdom of Saudi Arabia is the largest country on the Arabian Peninsula. It borders Jordan on the northwest, Iraq on the north and northeast, Kuwait, Qatar, Bahrain, and the United Arab Emirates on the east, Oman on the southeast, and Yemen on the south, with the Persian Gulf to its northeast and the Red Sea to its west. It is called "the land of the two holy mosques", a reference to Mecca and Medina, Islam's two holiest places.
