A group of quarrying tools was recovered from Area B of the Third Wall excavations, approximately 400 m northwest of Damascus Gate, Jerusalem. The tools were found side-by-side, one atop the other, and therefore, seem to be part of a stonemason’s tool kit. Among the tools are splitting wedges and wedge slats. This is the first time that so large a group of ancient quarrying tools has been exposed in situ in an archaeological excavation. The tools were probably used in a quarry dating to the Second Temple period.
