Napa State Hospital holds civil and forensic mental patients in a sprawling 138-acre campus.

Originally named Napa Insane Asylum, the facility opened on November 15, 1875.

It sat on 192 acres (0.8 square kilometers) of property stretching from the Napa River to what is now Skyline Park.

By the early 1890s, the facility had over 1,300 patients which was more than double the original capacity it was designed to house.

Facilities on the property included a large farm that included dairy and poultry ranches, vegetable garden, and fruit orchards that provided a large part of the food supply consumed by the residents.
