Umm al-Jimal

Umm al-Jimal, nicknamed the 'black gem of the desert', is a remarkably preserved rural town on the basalt steppe of northern Jordan, built almost entirely from the region's dark volcanic stone. Its earliest structures reach back to the 1st century CE, when the area lay within the Nabataean kingdom, but the town flourished as an organically grown settlement from around the 5th century CE, on the site of an earlier Roman outpost, and remained inhabited until the end of the 8th century. Its houses, churches, barracks and reservoirs display the distinctive corbelled basalt architecture of the Hauran, with Roman military buildings later repurposed by Byzantine and early Islamic townsfolk. An elaborate water-catchment system sustained farming and herding across the surrounding land, and a rich body of inscriptions in Greek, Nabataean, Safaitic, Latin and Arabic records the shifting beliefs and communities of its people over many centuries. It was inscribed on the UNESCO World Heritage List in 2024.
