Fremont first opened in 1924. Known in the community for its striking architecture and large quad with a working water fountain in the middle, the San Fernando Earthquake of 1971 forced many buildings on campus to be torn down and rebuilt in a more traditional, earthquake-safe style. Once enrolled with more than 5,000 students in the early 2000s, Fremont reduced its number of students when South Region High School 2 opened in 2011.
