In the 1880's, Boyle Heights emerged as a streetcar suburb of Los Angeles inhabited by artisans and white-collar workers. In the 1920's, the neighborhood was predominantly Jewish and, by 1940, the Jewish population had reached 150,000. Reminders of this era still remain -- a massive brick synagogue, for example, still stands near the intersection of Breed Street and Cesar Chavez Boulevard (formerly Brooklyn Avenue). Since World War II, the population has become predominantly Latino and mainly of Mexican descent.     Boyle Heights lies along the eastern bank of the Los Angeles River. Along with several other neighborhoods, including Lincoln Heights, City Terrace, Maravilla, and Belvedere, it forms the heart of the larger region known as "East Los Angeles".     View a map Boyle Heights
