 It continued to be used as a burial place for non-Jews up to the first quarter of the 19th century.During the era of the Crusades, it was used to bury the fifty or more patients who died each day in the hospital run by the Knights Hospitaller in Jerusalem.In the 12th century, the crusaders erected beyond the field, on the south side of the valley of Hinnom, a large building now in a ruined condition, measuring seventy-eight feet in length from east to west, fifty-eight feet in width and thirty in height on the north.
