This triangular staircase is located in the Arthur Rubloff building on the Campus of the School of the Art Institute of Chicago. These are the main stairs down to the lower level where the sculpture workshops and dance dance hall is located. However, it's marked about as well as the broom closet. I've only been in the building a few times, but it has to be one of the most confusing to navigate. The whole experience of being in the building is quite surreal. The art students have clearly made it their home.
