The oldest sorority still on campus, the Illinois Beta-Delta Pi Phi Chapter was founded in 1872 at Lombard College and in 1884 at Knox. As Lombard College collapsed in the Great Depression, the Beta and Delta Chapters were combined. A non-residential organization, they use their bungalow, or "the bung," for meetings, ceremonies, and siblinghood activities. It's located at 396 South Academy Street.
