Chateau-sur-mer was the most palatial residence in Newport from its completion in 1852 until the appearance of the Vanderbilt houses in the 1890s.
Chateau-sur-Mer's grand scale and lavish parties ushered in the Gilded Age of Newport. Chateau-sur-Mer was built as an Italianate-style villa for China trade merchant William Shepard Wetmore. It was the scene of many memorable entertainments, from the "Fete Champetre", an elaborate country picnic for over two thousand guests held in 1857, to the debutante ball for William's daughter, Miss Edith Wetmore in 1889.
Mr. Wetmore died in 1862, leaving the bulk of his fortune to his son, George Peabody Wetmore. George married Edith Keteltas in 1869. During the 1870s, the young couple departed on an extended trip to Europe, leaving architect Richard Morris Hunt to remodel and redecorate the house in the Second Empire French style. As a result, Chateau-sur-Mer displays most of the major design trends of the last half of the 19th century.
The house was purchased by the The Preservation Society of Newport County in 1969. In 2006 it was designated a National Historic Landmark. For more information on this Newport mansion visit this web site.
