An ancient limestone column lies in situ in the quarry from which it was extracted. Rejected by Herodian masons because it cracked midway along its length as it was being quarried out of the rock, the round megalith is evidence that the rectangular Temple Mount ashlars may have been initially cut round in order to roll them to their destination in the retaining walls of the Mount. This quarry is located in the Russian Compound of today’s Jerusalem.
