Madain Saleh (Hegra) is an important historical site in north-western Saudi Arabia, where famous inscriptions of the Nabataean civilization are found. This is a pre-Islamic archaeological site located near al-Ula, in the Province of al-Madina.
Several peoples have inhabited the area, beginning with the Lihyans and extending through the pre-Nabataeans, Nabataeans, post-Nabataeans, and Romans and up to the Arabic tribe of Thamud.
In early 2000, Saudi Arabia invited expeditions to carry out archaeological exploration, and the archaeological site was proclaimed a UNESCO World Heritage Site in 2008.
