Over a thousand years ago a great civilisation built a thriving metropolis in the heart of North America. It was larger than Paris, London and Rome at the time and was known as Cahokia. This vast city is one of the best kept secrets of western archaeology, but using cutting edge technologies like LIDAR Secrets: World's Greatest Pyramid can finally unravel its mysteries. Our investigators trace the rise and fall of this mighty civilisation which exploded into existence in 900 AD but vanished less than four hundred years later. Archaeologists John Kelly and Tim Pauketat explore the artifacts decades of excavations have unearthed at the site and what they teaches us about the culture and beliefs of the people here.
