Auditorium - Largest Concrete Building in the World - Los Angeles, California

After doing a little research I discovered that the building was just known as the "Auditorium" until the Los Angeles Philharmonic moved there in the early 1920's. As it pertained to buildings, the title of "World's Largest" or "World's Tallest" was a moving target through the early part of the century. In typical Los Angeles style, there is a parking lot now in the Auditoriums former location.
