One of the most popular and controversial books of our time, The Da Vinci Code, by Dan Brown, has been printed in more than 30 different languages.
First published in March 2003, the fascination has not died down and a movie based on the novel was made, starring Oscar-winning actor Tom Hanks as Professor Robert Langdon.
Da Vinci Declassified - which was made in 2005 and written and directed by David Carr and David Comtois - takes a fresh, fast-paced and fun look at The Priory Of Sion.
Is it real? If so, who’s behind it and what are its real goals? And whose destinies are they ultimately out to control?
The programme takes viewers on a journey through two thousand years of European history and art, going on location throughout Europe to unravel intricate clues about the Priory.
