Madain Saleh, also known as Al-Hijr or Hegra is an ancient archaeological site located in the Al-Ula sector within the Al Madinah Region of Saudi Arabia. A sister city to Petra in Jordan, Madain Saleh is a relic of the Nabatean civilization, which thrived in the area between the 1st century BC and the 1st century AD. The site encompasses 131 rock-cut monumental tombs with decorated facades, featuring a mixture of influences from Pharaonic Egypt, the ancient Near East, and the Hellenistic world. It became Saudi Arabia's first World Heritage site when it was added to UNESCO's list in 2008. Madain Saleh serves as a key historical site with inscriptions and rock arts reflecting the rich cultural heritage of the Nabateans. The site not only represents the Nabatean architecture but also their proficiency in water management. The desert landscape around Madain Saleh is stark, with its massive rock formations lending an air of mystery and grandeur to the ancient city.
