We drive for 30 minutes to Ad-Diriyah, located on the western bank of the Wadi Hanifah, a dry riverbed where water flows only after big rains. Ad-Diriyah used to be the capital of the Najd (the central plateau of the Arabian Peninsula) from the 15th century until the beginning of the 18th century. It is the birthplace of the first Saudi Kingdom and its importance in the history of the Arabian Peninsula was highlighted when it was listed as UNESCO World Heritage Site, in 2010, as the most brilliant example of Najdi architecture. The history of Ad-Diriyah goes back thousands of years as it was on an ancient trade and pilgrimage route, acting as a meeting point for those traveling to or from Asia, Africa, and Europe. As we drive towards the city, we have the opportunity to admire the rapid development of this cosmopolitan capital, planned by the Saudi government to become the biggest metropole in the Middle East in the next 10 years.
