On a small hill in Rum village, about 400m behind the Rest House (follow the telephone poles), are the limited ruins of a 2000-year-old temple, dedicated to the deity Lat. Inside the Rest House an information board describes the temple and its excavation. The ruins are important because they are evidence of a permanent Nabataean settlement, built on the earlier foundations of a temple built by the Arab tribe of Ad.
The baths in a villa behind the temple are the earliest so far discovered in Jordan. Near the temple are some inscriptions by hunters and nomads dating back to the 2nd century BC.
