Experience the Christmas décor of the gilded age starting Saturday at three of the Newport Mansions. The Breakers, The Elms and Marble House will each feature dozens of Christmas trees, wreaths and yards of garland as the holiday season approaches. Highlights include a historic Vanderbilt sleigh and topiary horse in the Great Hall of The Breakers, an 8-foot decorated wreath on the grand staircase of Marble House, and a 15-foot-tall poinsettia tree in the ballroom of The Elms. Guests may tour the properties daily through Jan. 1.
