Foellinger Auditorium
From U of I Wiki
Foellinger from the Quad
The Foellinger Auditorium is located at the very southern portion of The Quad and is one of the University's most recognizable buildings. It is the university's largest lecture hall, and also often hosts public lectures, concerts, and students performances.
On the lower floor of the building in the men's bathroom there is a door which serves as an entrance to the underground steam tunnels which go all around campus. Occasionally, a maintenance worker will leave the door unlocked and students can go inside.
