Moneta Branch, Mediterranean Revival library in South Los Angeles, United States.

Moneta Branch is a Mediterranean Revival library located in South Los Angeles, featuring a symmetrical brick facade with a central square tower and stucco finish. The structure showcases the architectural character typical of that style, with balanced proportions and classical detailing on its exterior.

The Moneta Branch began in 1908 as a book depository in a store, and in 1915 a formal branch opened in rented premises at 249 West 45th Street near Moneta Avenue, the street that gave it its name. The present Mediterranean Revival building opened in 1923. It was renamed the Junipero Serra Branch in 1934, closed after the 1987 Whittier Narrows earthquake, and has stood unused on Olive Street since.

The library functioned as a community gathering place during World War I, supporting neighborhood residents through Liberty bond distribution and Red Cross relief efforts. This reflects how public buildings of that era served functions beyond their original purpose as centers of civic engagement.

The 1923 building on Olive Street has been closed since the 1987 Whittier Narrows earthquake and is not open to visitors; its exterior, including the central square tower, can be seen from the street. Library service is available at the replacement Serra Branch at Main Street and 46th Street, opened in 1998.

The Moneta Branch was added to the National Register of Historic Places in 1987 as part of a thematic group submission covering several Los Angeles branch libraries. The application described it as a one-story Mediterranean Revival building of brick with a stucco finish, a symmetrical front facade and a square central tower. It has stood closed on Olive Street since the 1987 earthquake.
