A secret structure at Petra, Jordan, 2016
Modern technology has helped researchers uncover a giant platform of a similar size to an Olympic swimming pool at the ancient city and UNESCO site of Petra. After poring over satellite and drone images, archaeologists noticed a large rectangular structure not far from the famous Treasury.
It’s thought that the structure was once lined with columns, and experts muse that it could have been a holy building, or some sort of public administrative building. One thing they agree on is that they’ve never found anything similar at the site.
