When the third Marquess of Bute (1847 - 1900) met the renowned Gothic designer William Burges it marked the start of a lifetime's collaboration with architects and artists, producing work ranging from the High Victorian Gothic exuberance of Cardiff Castle and Castell Coch to the ostentation of Mount Stuart on the Isle of Bute and the sumptuous restoration of the Renaissance Falkland Palace. This fascinating biography tells the story of a rich eccentric, whose learning, insight and kindness produced extraordinary results in architecture and life, a man who combined being amongst the richest men of the age with artistic patronage of an almost incomprehensible scale.
