This dense jungle in Guatemala was once the heartland of the Mayans - an ancient civilisation that controlled much of Central America. Now, more than 1000 years after their empire collapsed, archaeologists have made a stunning discovery - this eight-metre-long frieze. The sculpture shows a divine governor who may once have ruled over Holmul - a mysterious city that once stood here. The sculpture sits beside a 1,500 year-old pyramid, but experts haven't said exactly how old the art work is.
