Mada’in Saleh, also called Al-Hijr or Hegra, is a pre-Islamic archaeological site. A majority of the vestiges date from the Nabatean kingdom (1st century CE). The site constitutes the kingdom’s southernmost and largest settlement after Petra, its capital. Traces of Lihyanite and Roman occupation before and after the Nabatean rule, respectively, can also be found in situ.In 2008, for its well-preserved remains from late antiquity, especially the 131 rock-cut monumental tombs, with their elaborately ornamented façades, of the Nabatean kingdom, UNESCO proclaimed Mada’in Saleh as a site of patrimony, becoming Saudi Arabia’s first World Heritage Site.
