DESCRIPTION: Castles in the Air is a beautifully written, autobiographical story of rescuing an ancient mansion. Gwydir Castle was inhabited by ravers and rats until Judy Corbett and her husband Peter Welford found and acquired this 500-year-old house mouldering in the foothills of Snowdonia. Despite the toads, strange smells and squatters, they decided to mortgage themselves to the hilt to bring the castle back to life.
