Terry Jones' Great Map Mystery (2008) watch online

Terry Jones' Great Map Mystery is a four-part television documentary series first broadcast on BBC Two Wales in 2008 and presented by former Monty Python member Terry Jones. As described on the BBC's website, "Terry Jones sets out on a series of journeys through Wales following the world's first road atlas: John Ogilby's Britannia, published in 1675."

In the series, Jones argues that Britannia was secretly designed to serve as a carefully coded blueprint for a French invasion of Britain that had the knowledge and covert support of Charles II.
