MacArthur Park is a park dating back to the late 19th century in the Westlake neighborhood of Los Angeles. In the early 1940s, it was renamed after General Douglas MacArthur, and later designated City of Los Angeles Historic Cultural Monument#100.The lake in MacArthur Park is fed by natural springs. In the past, a fountain with a reflecting pool on the northern end was also fed by the springs. The Westlake/MacArthur Park B and D Line station is across the street.
