Built 1964. Pimentel's circular lecture hall is on the cutting edge of classroom technology, including a revolving stage that allows multiple professors to teach, clean up, and set up at the same time, so that the room can be used continuously despite the long setup times involved in chemistry lectures.
Accessible entrances: There are two entrances to the building. The main entrance that faces west is usable but does not have automatic doors. In addition, Pimentel hall is accessed via corridor that links to Latimer Hall on the basement floor.
Restrooms: The nearest usable restroom is located in Latimer hall.
