Return to the halcyon days of the Gilded Age with this installment of the popular cable-TV series. America's über-wealthy upper crust made Newport, R.I., their summer playground, building magnificent mansions adorned with marble, ornate woodwork and solid-gold faucets. Featured are the 50-room Château-sur-Mer "cottage," Alva Vanderbilt's Marble House and the breathtaking 70-room palace known as the Breakers.
