The Hegra Archaeological Site (al-Hijr / Madā ͐ in Ṣāliḥ) is the first World Heritage property to be inscribed in Saudi Arabia. Formerly known as Hegra it is the largest conserved site of the civilization of the Nabataeans south of Petra in Jordan. It features well-preserved monumental tombs with decorated facades dating from the 1st century BC to the 1st century AD. The site also features some 50 inscriptions of the pre-Nabataean period and some cave drawings. Al-Hijr bears a unique testimony to Nabataean civilization. With its 111 monumental tombs, 94 of which are decorated, and water wells, the site is an outstanding example of the Nabataeans’ architectural accomplishment and hydraulic expertise.

The archaeological site of Al-Hijr is a major site of the Nabataean civilisation, in the south of its zone of influence. Its integrity is remarkable and it is well conserved. It includes a major ensemble of tombs and monuments, whose architecture and decorations are directly cut into the sandstone. It bears witness to the encounter between a variety of decorative and architectural influences (Assyrian, Egyptian, Phoenician, Hellenistic), and the epigraphic presence of several ancient languages (Lihyanite, Thamudic, Nabataean, Greek, Latin).

Criterion (iii): The site of Al-Hijr bears unique testimony to the Nabataean civilisation, between the 2nd and 3rd centuries BC and the pre-Islamic period, and particularly in the 1st century AD. It is an outstanding illustration of the architectural style specific to the Nabataeans, consisting of monuments directly cut into the rock, and with facades bearing a large number of decorative motifs. The site includes a set of wells, most of which were sunk into the rock, demonstrating the Nabataeans' mastery of hydraulic techniques for agricultural purposes. The testimony borne by Al-Hijr to…
