Turkish archeologists who have been working on excavations near Kilis since the 1960s have recently uncovered some exciting finds at an Iron Age settlement known as the Oylum tumulus, which they believe may contain the remains of the city of Ullis. A number of ancient texts suggest possible connections between this town and Abraham, indicating that Abraham may have stayed here for some time. Findings at the site suggest habitation in the region from as early as 3500 BCE. The nearby Kilis museum displays artifacts from a wide range of historical periods, beginning with the Paleolithic and Neolithic eras, continuing through the Bronze age, and reaching all the way to the Roman period and into the Middle Ages. An ethnographic wing showcases a traditional house in Kilis and traditional costumes from the area.
