John Patrick Crichton Stuart, the 3rd Marquess of Bute, was one of the richest men in the British Empire in the late 19th century.
With an annual income in excess of £150,000 - around £15 million in today's money - he pursued his passion for architecture with a vengeance. Narrated by Suzanne Packer, The Scot Who Spent a Welsh Fortune delves into the extraordinary world of Lord Bute and reveals what connects the small Scottish island of Bute to modern Cardiff.
Bute was one of the most unconventional mavericks of the Victorian age, passionate about the past but also far ahead of his time - a blue-blooded aristocrat, who supported women's rights and striking miners, a Welsh-speaking intellectual Catholic who was also a ghost hunter. Above all, Bute was a fabulously rich and visionary creator of great architecture including the Gothic fantasy of Cardiff Castle, and Castell Coch - the fairytale castle.Great stuff and you have only got one day left to catch it on the BBC iPlayer.
