In the 1891 Sonoma's first high school used the three-story Cumberland College building located on Broadway. During the eight years of its existence, the college flourished and had at one time as many as 400 students, mostly from other parts of California and nearby states. It was closed when the State University of California campus opened in Berkeley. Sonoma Valley Union High School had its first commencement in 1894, graduating two students. The Principal from 1897 to 1901 was Benjamin Weed. San Francisco's 1906 earthquake tumbled buildings in Sonoma, among them the high school. Students attended classes in a church basement and the upstairs of Clewe's store on the corner of Broadway and Napa Street, until a new school was built on the foundation of the old Cumberland College. Classes, varying in size from three to more than a dozen continued in this building. Over time, the campus was transformed through a number of building projects. The high school is still in existence and remains the only high school in Sonoma. In 2018, the school served over 1300 students.
