Auditorium Building and Music Hall, 1894
You have to really be looking to find traces of the original "Auditorium Building" sign painted at the top of the building. It's now so faded that it's almost unreadable. Originally, the building was occupied by a liquor store on the first floor, dance hall on the second, and a concert hall on the third and fourth floors. It's still a fine looking building.
You can see this from the street at SW 3rd between Salmon and Taylor, or for a closer look, head up to the sixth floor of the parking lot across 3rd Avenue.
