Archeologist Eli Shukron, formerly with the Israeli Antiquities Authority, stands in an ancient water spring that is surrounded by a 3,800 year old fortification wall in the City of David Archaeology Park outside the Old City of Jerusalem, Israel, May 7, 2014. Shukron claims he has found the citadel captured by King David when he captured Jerusalem after excavating the site for nearly two decades. He says the massive fortification wall surrounding the water spring that he discovered during excavations is the Citadel of King David, the Citadel of Zion. UPI/Debbie Hill
