She is founder and president of the Unicorn Foundation, to which profits from the film were contributed.
By carbon-dating bits of wood from the internal structure of the towers, she confirmed that they were built 500 to 1,800 years ago.
The fact that many of the towers have survived hundreds of earthquakes and tremors over the years, is probably due to their star-shaped design as well as to their construction method which intersperses masonry with wood planks or beams – an anti-seismic technique specific to this part of China and still employed in the region today.
Combined with the vast numbers and size of the towers, this is evidence that a sophisticated civilization once existed in these remote areas.
Darragon believes these areas are now sure to become a major tourist attraction and has lobbied for the towers to be listed as a UNESCO World Heritage Site for their protection and preservation.
