Carolands Chateau is a 46,050-square-foot (4,278 m²), 4.5 floor, 98 room mansion on 5.83 acres (2.36 ha) in Hillsborough, California, United States. An example of American Renaissance and Beaux-Arts design, the building is a California Historical Landmark and is listed on the National Register of Historic Places. Carolands is one of the last of the houses built during the Gilded Age, a period of great mansion-building that included famous houses of the Vanderbilt family, such as Marble House, Biltmore Estate and The Breakers, and stately California houses such as Filoli and the Huntington family's mansions.
