Stepan Center
The folks at Stepan Chemical supply obviously were playing a cruel joke on Notre Dame when they donated this structure. The building is shaped like a geodesic dome on top (like the EPCOT ball, but not as classy) and houses basketball courts. Oddly, the Student Union Board (SUB) stages most of their student concerts in this building. The acoustics are the worst, and the music turns cacophonic.
This building is not to be confused with Stepan Chemistry Hall.
