Approximately four kilometers east of modern Beer Sheva, is Tel Be’er Sheva, which some scholars identify as the biblical Beer Sheva. However, the earliest structural remains excavated dates to a period later of that of the Avot
Perhaps the most interesting find in the excavations was a horned altar. In ancient times, the altar was dismantled and its stones used to build a store house. Based upon the archeologist’s dating, it can be assumed that the altar was dismantled as part of the religious reform of KIng Chizkiyahu as related in Tanach. [Melachim II Perek18 Posuk 4]
.Outside the gate of Tel Be’er Sheva, there are remains of a sixty-nine meter (226 feet) deep well, which may be the well mentioned in connection with Avraham and Yitzchak Avinu
