Outsiders are not very clear about the history of this building, I think the building is relatively old.
On Michigan Avenue in Chicago, facing the direction of Buckingham Fountain, there is a ten-story building—Auditorium Building, which translates as "hall building" or "auditorium building". Very inconspicuous among the skyscrapers on Michigan Avenue. The gray exterior, three low arches, and a more inconspicuous side door beside it. Although inconspicuous, not many people come here. Enter the main entrance (arch), Roosevelt University, you can visit. Entering the side entrance is the headquarters of the famous Chicago Symphony Orchestra. People who carry instrument cases often come in and out from here. If you are not careful, you might meet a musician. The elevator inside is also old-fashioned. The following pictures are the interior view of the hall building
