Ruins at Jacob’s Well
In the valley of Shechem, near to a city called Sychar, was the well where the Lord rested, and conversed with the woman of Samaria (John 4:5-42). It is identified with Bir Yakub, at the base of Gerizim, 32° 12' N, 35° 16' E, and is one of the few spots in Palestine the identification of which has not been disputed.
Jacob’s Well – Interior
The well is cut out of the solid limestone, 7ft. 6in. in diameter, and is now about 75 feet deep; but early travelers give the depth as much greater. Every visitor casts in stones to hear them reach the bottom. It is only in the winter that there is now any water in it. The well’s mouth is below the surface of the ground and is covered with a stone with a hole in the center. A traveler, John of Wurzburg (A.D. 1160-1170), says that when he visited the well a church was then being erected over it; but that has long since been destroyed. See SYCHAR.
