Chateau sur Mer is one of the 9 mansions operated by the Newport Preservation Society. The mansion has free parking and is on Bellevue Ave. right by the local bus/trolley. Bellevue is a beautiful street with many large mansions. Chateau sur Mer was built in the 1850s by the Wetmore family whose son George, who was both a governor and senator, inherited the mansion and had it remodeled in the 1870s. The grounds are large and park like and the building is old fashioned and very lavish with beautiful wood and wonderful furnishings. It is not as opulent as the Breakers or Marble House, but is certainly worth a visit. The tour guide was an older man, with a very dry, witty sense of humor, who told wonderful stories about the family and the house. If you are visiting more than 1 or 2 mansions, the package tour of 5 mansions for $31 is a bargain since the mansions can be visited at any time and there is no time limit.
