Countryfile is in the county of Northamptonshire. Matt Baker is exploring a section of the Grand Union Canal and finding out about the huge amount of work that goes into keeping it ship-shape for the thousands of visitors who come every year. Julia Bradbury is discovering some of the hidden heritage of the county. Her first stop is Rushton Triangular Lodge - a folly built by a Catholic in the 16th century. She then travels to Canons Ashby - another house full of symbolism but this time it's the illuminati at work. Julia will also be visiting a farm on the site of a scheduled listen monument where the farmers have a unique take on diversification. They make gin from the spring water that flows through the land and claim to be the only artisan gin makers in Northants
