How did the Romans produce some of the most impressive gladiatorial games ever seen in Europe? How did the Colosseum's mysterious roof really work? And how does the mighty Colosseum compare to the popular sports venues of the 21st century? Structural engineer Steve Burrows and his team of laser-scanning experts head to Rome on a quest to answer these questions and uncover some of the oldest mysteries of the ancient stadium.

Using cutting-edge, 3D laser-scanning technology, structural engineer Steve Burrows leads his team of experts into the Peruvian jungle to scan the sacred Inca city of Machu Picchu, asking three main questions: How did the Inca build a city atop a mountain ridge? How were the terraces constructed? And how did they supply water to the city? Join the team as they turn back time and decode the past.
