Torrance School, Renaissance Revival school building in Torrance, California, US

The Torrance School, also called the Torrance High School Annex, is a Renaissance Revival building constructed from 1923 to 1925 on the southern side of the Torrance High School campus. A long curving arcade with a pillared center links it to the rest of the campus.

The building opened in 1923 as Torrance Elementary School, serving the community's younger students during the city's early expansion period. By 1963, it was repurposed as a high school annex to meet growing educational needs.

The building's names track its changing roles: opened in 1923 as Torrance Elementary School, it became the Torrance High School Annex after a new elementary campus was built off site in 1963. Torrance elementary schools belonged to the Los Angeles City School District until 1947, then to the new Torrance Unified School District, renamed in 1948.

The building sits on West Carson Street and is accessible by car or public transit in the Torrance area. Since it remains active as part of a school campus, visiting the grounds works best outside of regular school hours and during breaks.

It is one of four campus buildings designated on the National Register of Historic Places since 1983, making the entire complex a recognized historical landmark. This distinction reflects the architectural and educational value the site holds for California's development.
