You've probably heard of the oldest college in the United States, Harvard University. But you may not have heard of the third-oldest, St. John's College.

Founded in 1696, St. John's is a private liberal arts college with a emphasis on classical philosophy and literature. The school has two campuses, one in Annapolis, Maryland and one in Santa Fe, New Mexico, which enroll a total of 896 graduate and undergraduate students. All classes are taught seminar-style, and students do not have majors.
