Claire McCollum visits the city of Perth on the banks of Scotland's longest river, the Tay. She meets Lady Mansfield at Scone Palace and finds out more about its role in the country's religious history. Once a large abbey and religious community, it was the site of the Scottish Parliament and the crowning place of Scottish kings. We also mark 175 years since the Free Church of Scotland was established in an event known as The Disruption and reveals the story of how its founding inspired early photography. JB Gill meets local minister, the Rev Scott Burton, whose passion is kayaking on the River Tay. He explains to JB how the river has taught him many lessons, brought alive biblical imagery and helped shape his life and faith.
