"To Place of Trumpeting" Sign    
This inscription, which translates as "To the place of trumpeting..." was discovered during B. Mazar's excavations at the base of the Herodian wall at the southwest corner of the Temple Mount.  It served to indicate where a priest would stand to blow the trumpet to begin and end the Sabbath; that place was probably along the parapet (a low, protective wall) on top of the outer wall.
