Tarout Island is also a wonderful place to see as its history was built up over almost 5,000 years. Qasr al-Darin was built to protect the pearl trade which the area was famous for. There is also a fort made out of the traditional mud and brick design. The Aramco Exhibit located in Dhahran is an excellent display about oil production and the history behind the Aramco Company. The well designed exhibit is worth a visit for all those new to the area. This area, rich in history and resources is also the site for the King Saudi Abdulaziz University for Health Sciences Al Ahsa branch for the College of Nursing and the College of Applied Medical Sciences. The efforts of the University are improving the quality and quantity of qualified staff to care for the health needs of a growing nation.
