Hegra's 111 monumental tombs were carved between the first century BCE and the first century CE, yet the site received fewer than 200 annual visitors until Saudi Arabia opened its borders to international tourism in 2019.
The Nabataean kingdom controlled incense routes linking Yemen to Mediterranean ports, and Hegra—ancient Hegran, later Madain Saleh—served as the southern capital where merchants paid customs duties and watered camels before the Petra crossing. UNESCO inscription arrived in 2008, making this the kingdom's first World Heritage Site, yet the necropolis remained closed to casual visitors for another decade while conservators stabilized façades eroded by fifteen centuries of sandstorms.
The tombs face east and south to capture winter sunrise, their pediments and pilasters mimicking Hellenistic temples though no interior worship space exists—Nabataeans buried their dead in rock-cut chambers and sealed the doorways forever. Qasr al-Farid, the site's most photographed monument, stands four storeys tall and entirely alone on a sandstone outcrop, its name translating to Lonely Castle. The tomb was never finished; tool marks remain visible on the lower register where masons abandoned work when Hegra's trade dominance collapsed after Rome annexed the Nabataean kingdom in 106 CE. Archaeologists have identified 94 Nabataean, Lihyanite, Thamudic and Greek inscriptions across the site, including a 17-line curse tablet warning grave robbers of divine retribution.
Evening access allows visitors to experience the tombs under controlled LED illumination that mimics moonlight—white and amber washes bring depth to the stone without the harsh contrast of midday sun. The Royal Commission for AlUla limits daily visitor numbers to 650 and restricts photography drones to protect the fragile sandstone, which continues to erode at 2-4 millimetres per decade despite interventions. Guided tours follow a 2.2-kilometre circuit connecting Tomb 67, the Diwan chamber where tribal councils convened, and the Hijaz Railway station built by Ottoman engineers in 1907 and shelled by T.E. Lawrence's forces nine years later. The railway corridor now serves as a pedestrian promenade lined with interpretive plaques detailing Nabataean hydraulic engineering—Hegra's 130 wells and stone-lined cisterns sustained 2,000 residents in a landscape receiving less than 50 millimetres of annual rainfall.
