Structural engineer Steve Burrows leads his team of laser-scanning experts to Jordan in the Middle East, on a quest to scan the ancient desert city of Petra. Using their cutting-edge 3D laser-scanning technology, they are exploring and analyzing Petra in a way that’s never been done before to find answers to mysteries like: How did Nabatean stonemasons carve Petra’s largest building – the Monastery – out of a mountainside? Was Petra’s city center - the “Southern Terrace” all built at the same time as part of on huge construction project, or in different historic periods? And what secrets lie hidden underneath the Monastery’s huge courtyard? The team’s laser scans bring fresh answers and breath taking new finds to this ancient city.
