Westlake Park Renamed MacArthur Park on May 7, 1942.

Westlake was one of the first areas of Los Angeles west of Figueroa Street to see residential development. By the 1920s, Westlake resembled the Upper East Side of Manhattan (complete with a large Jewish population). Wealthy businessmen commuted to downtown, Wilshire Center (now Koreatown), Hollywood, and the Miracle Mile from the district's Spanish Revival and Art Deco mansions. The district's less affluent northeastern blocks also became the home of Los Angeles' Filipino population, much of which remains in Westlake and nearby neighborhoods to this day.

Westlake Park was renamed MacArthur Park on May 7, 1942.
