Jacob's Well; Well of the Samaritan Woman
(Hebrew: Bir Yakub; Bir Samariyeh)
Well on the highroad from Jerusalem, one mile and a half from Nablus, and almost one mile from the village of Askar or Sichar (John 4).
Here Christ met the Samaritan woman.
It is called Jacob's Well because the patriarch who "drank thereof himself, and his children, and his cattle" gave it to the tribe of Joseph.
The opening of the well lies now in a crypt of a Crusader's chapel, over which the Greeks have built a church.
The well itself is 7.5 feet in diameter, lined with masonry, and is still 75 deep.
It seems to be fed by an underground rivulet, which occasionally runs dry in summer.
