Eugene O'Neill National Historic Site

Eugene O'Neill National Historic Site is a residential house with Eastern-influenced architecture set on about 13 acres in Contra Costa County. The building features dark blue ceilings and wooden floors that define the living spaces.

The house was built in 1937 using Nobel Prize funds and became a National Historic Landmark in 1971. It received National Historic Site status in 1976.

The house is named Tao House, reflecting the playwright's deep connection to Eastern philosophy. Visitors can see today how these ideas shaped the rooms through the chosen decorations and the way the building was designed.

Visitors must book in advance to tour the site, as entry is by reservation only. A free shuttle service runs from downtown Danville, and private vehicles are not allowed to reach the house.

The interior displays traditional Noh masks and Chinese guardian statues that show how deeply the resident was inspired by Eastern aesthetics. This collection was more than decoration—it reflected his artistic thinking.
