Jewish-Roman historian Josephus, as well as Christian and Jewish sources from the Byzantine period, locate Mamre at the site later renamed in Arabic as Ramat el-Khalil, 4 km north of historical Hebron and approximately halfway between that city and Halhul. Herod the Great apparently initiated the Jewish identification of the site with Mamre, by erecting there a monumental enclosure. It was one of the three most important "fairs" or market places in Judea, where the fair was held next to the venerated tree, accompanied by an interdenominational festival joined in time by Jews, pagans, and Christians. This prompted Emperor Constantine the Great to unsuccessfully attempt at putting a stop to this practice by erecting a Christian basilica there.
