Baldwin and his wife. It is a wood-frame, stucco-clad building with a French-inspired design.","why_significant":"The nomination argues the building is a unique example of 16th-century French architectural influence, modeled on the Trianon at Versailles, particularly in its doors, windows, columns and shutters. It is also tied to prominent owners and the Baldwin wine estate. It was planned as a California history museum and research center for the college district.","narrative":"Built in 1892 for Charles A. Baldwin and his wife Ellen Hobart Baldwin, Le Petit Trianon is a wood-frame mansion with a stucco exterior and wooden columns, pilasters and shutters, located on the De Anza College campus in Cupertino. Its doors, windows, columns and shutters echo the Trianon architecture near Versailles, giving it a distinctive French character. The Baldwins' 137-acre estate became a well-known wine-producing property. In 1909 the house passed to Harriet Pullman Carolan, who hosted lavish entertainments there around the time of the 1915 Panama-Pacific Exposition. It was later sold in 1940 to E. F. Euphrat, and the Foothill district then acquired it for the college with the understanding that it would be preserved. Interior wainscoting, trim, mouldings and parquet flooring remain largely intact. The building was moved a short distance and set on cribbing while funds were sought to restore it as a California history museum and research center.","period_of_significance":"1892","architect_builder":"Built by Charles A.
