A water tunnel dating back to the First Temple era - but that might have been used even earlier, during King David's conquest of Jerusalem - has been uncovered in the ancient City of David. The opening of the 3,000-year-old tunnel, which was found earlier this year during the ongoing excavations at the site, is just wide enough to allow one person to pass through, but only the first 50 meters are accessible since it is filled with debris and fallen stones, said Dr. Eilat Mazar.
