More4's The Great British Dig presenter Hugh Dennis visits Shaw House in Newbury for new series

The first episode of series three of The Great British Dig: History in you back garden tries to uncover the secrets of a tudor hall in Odiham.

During the programme, presenter Hugh Dennis makes a trip to Shaw House in order to discover more about Elizabethan architecture.

In the episode, Hugh and the archaelogical team search for the house of the head of the Elizabethan Secret Service – Sir Frances Walsingham – in Odiham, Hampshire.

Walsingham was Queen Elizabeth's trusted spymaster and the only evidence the team have of his home in Odiham is a map from 1739, sketched almost 150 years after his death.

It's the first time the site has ever been dug and the team of experts – comprised of archaeological scientist and lecturer at Newcastle University Dr Chloe Duckworth, archaeologist Richard Taylor and field archaeologist Natasha Bilsonwant – want to locate the house, work out its size and scale, and what Walsingham may have used it for.

As part of the investigation, Hugh turns his hand to spy craft as he learns how Walsingham used to break codes, and also visits Shaw House, one of the best-preserved Elizabethan mansions in England.

Business Development & Marketing Manager for Culture at West Berkshire Council Becky Scantlebury said: "The filming took place in September last year, with Hugh Dennis presenting a brief description of the Elizabethan architecture which was shot from the front of Shaw House."

Posting on Twitter, the team at Shaw House said: "We are very excited to be featuring on The Great British Dig! Look out for Shaw House on the episode ‘A Lost Tudor Hall of Odiham’"

The Great British Dig: History in you back garden is broadcast on More4 tonight, Monday, April 11, at 9pm.
