Mary Ann Cofrin (MAC) Hall is one of the busiest buildings on campus. The instructional building was completed in 2001 and is utilized by several schools within the college, including the College of Arts, Humanities and Social Studies, the Austin E. Cofrin School of Business, and the College of Science, Engineering, and Technology. It serves as an important link, filling a gap between the Cofrin Library and the University Union. However, most students would be surprised to learn that the linchpin of MAC’s design was not any of these attributes – it was to house a pair of scientific collections. The Carl Richter Museum and the Gary Fewless Herbarium sit on the concourse level, tucked off the beaten path. Both offer a unique experience on campus, and the Richter holds a whole building’s worth of history inside its couple of rooms.
