Robson Green is given a fascinating history lesson in next week’s More Tales from Northumberland show.
Entitled Hidden Treasures, episode four sees the TV star learn more about the county’s heritage.
First off, he heads to the Farne Islands to go diving for shipwrecks and discovers some mysterious cannons and the wreck of a ship sunk by the German Luftwaffe in 1941.
He also finds out about the fascinating Roman relics that have been unearthed in the region, like the Corbridge Hoard, discovered by students in the 1960s, and the Vindolanda Tablets - the oldest handwritten documents in Britain.
Finally, Robson visits Holy Island to learn about the Viking invasion of the island and hears about the legacy left behind by the Norse invaders.
Episode four will be screened this Monday at 8pm on ITV.
More Tales from Northumberland sees Robson return to his home county for a second series of the popular show.
Having visited many of the county’s most famous landmarks on his last trip – broadcast in 2013 – this time he’s uncovering the hidden gems of the Secret Kingdom.
He explores parts of the county he’s never been to before – and some he didn’t even know existed – from its remote valleys and mystical ruins, to the hidden history of its castles and stately homes.
Robson has already encountered plenty of things during the first three episodes of the weekly, eight-part second series, which launched last month.
This includes a skinny dip at Druridge Bay, trying his hand at Cumberland and Westmorland wrestling at Powburn Show, learning more about a surfing seal off the coast of Amble and discovering the incredible hermitage at Warkworth.
