198 Young is the main lecture hall of Young Hall. If you are a Psychology or Anthropology student, you will most likely end up in this lecture hall many times for your classes. The hall seems to make a lot of people sleepy as evidenced by the graffiti that turns element Os to sOs on the northern periodic table. Young 198 is also where meetings of the student organization Filmmakers' Ambitions are currently held.
According to the UCD Registrar's Office, the hall can officially seat 296 people and is the 4th largest lecture hall on campus.
