JORDAN: Archaeologists have discovered a massive monument in Petra city of Jordan that must be 2,000-year-old. The monument was revealed by the satellite imagery and drone photography. It is buried under the sand and measures tell that it is twice the size of an Olympic swimming pool. The archaeologists studied aerial images to distinguish details of the structures past glory. The oldest pottery found scattered around the site suggests the structure could be more than 2,150-years-old. “Petra is an outstanding site to test new survey technologies,” wrote archaeologists Sarah Parcak and Christopher Tuttle in a report titled Hiding in Plain Sight. “Even after two centuries of fieldwork in Petra and its environs, new discoveries and identifications of monumental structures continue to be made.” The monument is less than a kilometre south of Petra, the main city in southwest Jordan, which was named one of the seven new wonders of the world in 2007. “I knew something was there and other archaeologists – who have worked in Petra for the last, God knows, 100 years at least,” Tuttle told The Guardian. He said he knew of at least one other expert that had noticed something at the site. More than half a million tourists visit Petra each year which has been inhabited since prehistoric times. It was the capital of the Nabataean empire from 400 BC to 106 AD and remained unknown to the western world until the early 19th century. More recently, the city provided the backdrop for the 1989 film Indiana Jones and the Last Crusade.
