Lihyan Tomb, Ula, Saudi Arabia

Hegra known to Muslims as Al-Hijr (Arabic: ٱلْحِجْر), also known as Mada’in Salih (Arabic: مَدَائِن صَالِح, romanized: madāʼin Ṣāliḥ, lit. 'Cities of Salih'), is an archaeological site located in the area of Al-'Ula within Medina Province in the Hejaz region, Saudi Arabia. A majority of the remains date from the Nabataean Kingdom (1st century AD). The site constitutes the kingdom's southernmost and second largest city after Petra (now in Jordan), its capital city. The site has earned a reputation as a cursed place—an image which the national government is attempting to overcome as it seeks to develop Mada'in Salih for its potential for tourism. In 2008, UNESCO proclaimed Mada'in Salih as a site of patrimony, becoming Saudi Arabia's first World Heritage Site. It was chosen for its well-preserved remains from late antiquity, especially the 131 monumental rock-cut tombs, with their elaborately ornamented façades, of the Nabataean Kingdom. Wikipedia.org
