Le Petit Trianon, Historic mansion at De Anza College, Cupertino, United States

Le Petit Trianon is a two-story mansion on the De Anza College grounds that displays French baroque revival architecture with classical columns, pilasters, and wooden shutters throughout. The entire structure uses redwood, a durable local material that characterizes its exterior appearance.

Charles Baldwin built this mansion in 1892 as part of his wine estate, which produced premium wines under the Beaulieu label. The wines were exported as far as New York and London, making the property a symbol of California's prosperity in the late 1800s.

The name comes from the Grand Trianon built for Louis XIV; its columns, pilasters, windows and wooden shutters echo that French precedent. Since 1965 the house has stood on the De Anza College campus, and it now serves as the California History Center, whose Stocklmeir Library and Archives holds oral histories, photographs and student research papers on the Santa Clara Valley, all consulted on site.

The mansion sits on the De Anza College campus and is accessed through the California History Center, which regularly hosts exhibitions, lectures, and workshops. Visitors should check ahead to see what programs or events are scheduled during their visit.

The house was moved twice after 1968: first to clear space for the Flint Center theater, then again to make way for a parking lot. It was listed on the National Register of Historic Places in 1972, and restoration was completed in 1982.
