Dr Jago Cooper explores the ancient civilisation of Teotihuacan, which exploded into a position of dominance in the Americas almost 2,000 years ago.

Dr Jago Cooper explores the rise and fall of the forgotten civilisations of central America.

His quest takes him from the crystal blue seas of the Caribbean to the new world's most impressive pyramids, flying over the smoking volcanoes of Costa Rica and travelling deep underground in the caves of central Mexico.

He travels in the footsteps of these peoples to reveal their secrets and unearth the astonishing cultures that flourished amongst some of the most dramatic landscapes in the world.

In the final episode, Jago explores the ancient civilisation of Teotihuacan that exploded into a position of dominance in the ancient Americas almost 2,000 years ago. For hundreds of years this great city state was the biggest in the New World. Its rulers built monumental pyramids and temples and then went on to build a vast empire that was maintained through force. Yet the identity of the people who led this civilisation remains a mystery.
