After the virgin Mary was informed by the angel Gabriel that by “the power of the Highest” she would conceive “and bring forth a Son, and shall call His name JESUS” (Luke 1:31,35), she then went to visit her relative Elizabeth, who was at that time the 6-months expectant mother of John the Baptist. “Now Mary arose in those days and went into the hill country with haste, to a city of Judah, and entered the house of Zacharias and greeted Elizabeth” (vv. 39-40).
To be clear, the text does not specify which city of Judah in which Zacharias (the priest) and his wife Elizabeth resided. It was a city in the “hill country” of Judah. However the traditional site is that of En Kerem (spelling varies), located about 5 miles west of Jerusalem.
R. Riesner, in his entry entitled, “The Birthplace of John the Baptist” states,
To visit Elizabeth, Mary went “into the hill country [oreinē], to a city of Judah” (Lk 1:39). The Greek word describes the district around Jerusalem (Pliny Nat. Hist. 5.14). A literary tradition that can be traced back to the sixth century identifies the birthplace with En-Kerem (Arabic Ain Karim), seven kilometers west of Jerusalem (ELS 44ff.). Remains of two fourth-century churches indicate, however, that the tradition stretches back to a still-earlier time (GBL II.776). (Archeology and Geography. In J. B. Green & S. McKnight (Eds.), Dictionary of Jesus and the Gospels (p. 34). Downers Grove, IL: InterVarsity Press).

Of course the point not to be lost is that when Mary heard the wonderful news that she would become the mother of the Messiah, she traveled from her home in Nazareth to visit Elizabeth, wife of Zacharias the priest, in a city in the hill country of Judea. There Elizabeth “was filled with the Holy Spirit,” and spoke, significantly, not about her own child (John) but about Mary, and the child she would have: “But why is this granted to me, that the mother of my Lord should come to me?
Hopefully some of our photos can help visualize the area in which this important visit took place.
