Watch Secrets of the National Trust with Alan Titchmarsh Season 5 Episode 5 Online

At Tyntesfield, Alan learns about the rise of William Gibbs, who became the richest non-aristocrat in 19th-century Britain through the trade of guano - otherwise known as bird droppings. Meanwhile, Chef Tony Singh and presenter Miriam O’Reilly explore beyond the Victorian Gothic house to discover the estate’s gardens, while Louis Emerick visits Mr Straw’s House in Nottinghamshire where, like Tyntesfield, it seems as though time has stood still for almost a century.
