Huge lost city found in Mexican jungle

In the heart of Mexico, special technology has uncovered a huge, thousand-year old city the size of Edinburgh.

At one time the city, Valeriana, is thought to have been home to more than 30,000 Maya people.

Specialist laser technology discovered the city's ancient structure, hidden beneath a jungle.

The BBC's climate and science reporter Georgina Rannard takes a virtual look at what the city's magnificent structures could have looked like.
