In the early 20th century, there was no better example of a classic American downtown than Los Angeles. Since World War II, Los Angeles’s Historic Core has been “passively preserved,” with most of its historic buildings left intact. Recent renovations of the area for residential use and the construction of Disney Hall and the Staples Center are shining a new spotlight on its many pre-1930s Beaux Arts, Art Deco, and Spanish Baroque buildings.
