Radio 3 Breakfast concludes its journey through the north east of England at Tynemouth Priory and Castle - high up on a dramatic headland, overlooking the River Tyne as it enters the North Sea. Because of its strategic position, places of worship over the centuries have co-existed here with fortifications. Petroc Trelawny wanders around the ruins of the 11th-century priory, the Gatehouse, and the former gun batteries pointing out to sea. He hears about navigation along the Tyne, its bridges, and the industry of Newcastle and Gateshead. And Kathryn Tickell, foremost exponent of the Northumbrian pipes, plays live - taking listeners on a musical journey up the Tyne, ready for the BBC Proms weekend from The Glasshouse in Gateshead
