Bowes and his wife Joséphine Benoîte Coffin-Chevallier founded the Bowes Museum, which is of national status. Housed in its own ornate building, the museum contains an El Greco, paintings by Goya, Canaletto, Boucher, Fragonard and a collection of decorative art. A great attraction is the 18th century silver swan automaton, which periodically preens itself, looks round and appears to catch and swallow a fish.
