Los Angeles Plaza or Plaza de Los Ángeles is located in Los Angeles, California. It is the central point of the Los Angeles Plaza Historic District. When Spanish Governor Felipe de Neve founded the Pueblo de Los Ángeles, his first act was to locate a plaza for the geographical center from which his town should radiate. De Neve's plaza was rectangular in form—75 varas wide by 100 in length. It was located north of the church; its southerly line very nearly coincided with the northerly line of West Marchessault street. On this, the cuartel, the public granary, the government house and the capilla (chapel), fronted.

The Pico House is a historic building in Los Angeles, California, dating from its days as a small town in Southern California. Located on 430 North Main Street, it sits across the old Los Angeles Plaza from Olvera Street and El Pueblo de Los Ángeles Historical Monument.
