Umm al-Jimal's ruins lie in the Hauran, close to Bosra in Syria, and have yielded valuable information on Roman and Byzantine town planning. More than 100 houses and around 15 churches have been identified among the ruins, which are surrounded by a wall. A number of cisterns bear witness to the necessity of storing water given the rarity of rainfall. Finally, a Byzantine corner tower marks the site of a barracks, reflecting this small city's defensive role.
