California State University, Chico is the second-oldest campus in the twenty-three-campus California State University system. It is located in Chico, California, about ninety miles north of Sacramento. California State University, Chico is commonly known as Chico State or Cal State, Chico. On March 12, 1887, a legislative act was enacted to create the Northern Branch State Normal School of California. Less than a month later, Chico was chosen as the location. On June 24, 1887, General John Bidwell donated 8 acres (32,000 m²) of land from his cherry orchard. Then on July 4, 1888, the first cornerstone was laid. On September 3, 1889, doors opened for the 90 enrolled students. The library opened on January 11, 1890 with 350 books. On June 20, 1891 the first graduation took place, a class of 15. In 1910, Annie Bidwell donated an additional two acres (8,000 m²) of land to be used for work with elementary agriculture. The next year Mrs. Bidwell donated an orange orchard lot 55 × 440 feet (130 m) as the children's playground, which is connected to the Training School. Twenty years later in 1921, legislation was enacted to change the school's name to Chico State Teacher's College.
