Riddle Hall—Located beside South Hall on the east side of campus—Riddle Hall was built in 1928 and named for Henry Riddle, a trustee from 1900 to 1922. Renovations of Riddle were completed in 1995.

Riddle is the choice of many upper-class students and its suites are comprised of two double rooms (12' x 16') sharing a connecting bathroom (four students total per suite). There are also a few stand-alone double rooms as well as a few single rooms (12' x 11'); some with private bathrooms, a sink and vanity combo, or sharing a "common" bathroom on the hall. Riddle also offers several student lounges, computer lab and a fully-equipped kitchen space.
