The Castle is now the beautiful home of James Saunders Watson and his family. Julie tours the interior of the castle; the Great Hall, Library, Panel Room, and Long Gallery, all of which have evolved to the needs and tastes of each generation who have lived here. Some surprise family connections are revealed as well.
