The 13–acre Eugene O'Neill National Historic Site commemorates the only Nobel Prize–winning U.S. playwright, through preservation of the Tao House. A Spanish–colonial structure with an interior scheme inspired by Chinese Taoism, this building served as the home of O'Neill and his wife Carlotta between 1937 and 1944. Eugene O'Neill (1888–1953) is the author of The Iceman Cometh, Long Day's Journey Into Night, and A Moon for the Misbegotten, among other works. His pieces introduced realism to American drama, were among the first U.S. plays to include speeches in the vernacular, and are populated with marginalized characters.

The site offers guided tours of the Tao House, self–guided tours of the grounds, and twice yearly presentations of O'Neill's plays. Reservations are required to enter the house.

Walter Gropius, founder of the German design school known as the Bauhaus, was one of the most influential architects of the 20th century. He designed this house as his family home in 1937, when he came to teach at Harvard's Graduate School of Design. Modest in scale, the house was revolutionary in impact. It combined the traditional elements of New England architecture—wood, brick, and fieldstone—with innovative materials rarely used in domestic settings at that time—glass block, acoustical plaster, and chrome banisters, along with the latest technology in fixtures. In keeping with Bauhaus philosophy, every aspect of the house and its surrounding landscape was planned for maximum efficiency and simplicity of design. The house contains an important collection of furniture designed by Marcel Breuer and made for the Gropiuses in the Bauhaus workshops.

The house offers tours and educational and recreational programs.

California's executive mansion, popularly known as the Governor's Mansion, was built in 1877 for Albert and Clemenza Gallatin. Albert was a partner in the Sacramento hardware store of Huntington & Hopkins. The State of California purchased the house from Joseph and Louisa Steffens to use as a home for California's first families in 1903 for $32,500. Victorian architecture was somewhat out of style by then, but the house was suitably impressive, conveniently located, and comfortable. Today's guests see marble fireplaces from Italy, gold-framed mirrors from France, and exquisitely handcrafted hinges and doorknobs, all of which are reminders of the Gallatins and the Victorian era. Outside some of the Mansion's abundant vegetation includes flowers, shrubs, and trees dating back to 1877. When visitors look behind the grape-stake fence and see Governor Brown's swimming pool built in 1959, they are reminded that the Governor's Mansion State Historic Park is really a walk through time.

The park offers tours and occasional recreational and educational events.
