Carolands is California Historical Landmark No. 886, and listed on the National Register of Historic Places. The 98-room Château completed in 1916 is situated on over five and one half acres of land in Hillsborough.

Harriett Pullman Carolan (1869-1956) was the daughter of George Pullman, the 19th century American industrialist, who became one of the wealthiest men in Chicago after creating the Pullman Company, famous for its Palace railway cars. Perhaps because her father was one of the inventors of modern "luxury" or "first class" travel, Harriett Pullman came to expect perfection and beauty in her surroundings. In Chicago in 1892, Harriett Pullman married Francis Carolan of San Francisco and moved with him to California. In 1912, Mrs. Carolan acquired over 500 acres of land on which to build her dream house. She had been actively planning to create a house and garden that would excite "the wonder and admiration of America" and reflect her refined and cultivated interests. The result was an authentic Beaux-Arts architectural masterpiece, inspired by the court architecture of Louis XIV. The property was situated at the highest local geographical point in order to command the best views of the Bay and surrounding hills.

The Château exterior was inspired by the 17th century designs of

François Mansart. The project was executed by San Francisco architect Willis Polk, following plans commissioned by Mrs. Carolan from the Parisian architect Ernest Sanson, who was at the time one of the foremost designers of prestigious private homes in France and perhaps the world. Sanson, age 76 and near the end of a long and distinguished career, never visited the California site. Willis Polk, a distinguished American architect in his own right, was engaged to be the structural designer and manager of construction. He was instructed by Mrs. Carolan to execute Sanson's French plans faithfully. The gardens were designed by the leading French landscape architect Achille Duchêne. He was inspired by the great 17th century works of André Le Nôtre whose most famous creations are the Palace of Versailles, Vaux-le-Vicomte and the Jardins des Tuileries. Duchêne's original designs consisted of many thousands of trees and shrubs, with plans for fountains, statues, and roadways.
