Gimghoul, a secret society headquartered at the Gimghoul Castle. The order was founded in 1889 by Robert Worth Bingham, Shepard Bryan, William W. Davies, Edward Wray Martin, and Andrew Henry Patterson, who were students at the time. The society is open to male students (rising juniors and higher), and faculty members by invitation. The society centers itself around the legend of Peter Dromgoole, a student who mysteriously disappeared from the UNC campus in 1833. The founders originally called themselves the Order of Dromgoole, but later changed it to the Order of Gimghoul to be, "in accord with midnight and graves and weirdness", according to the university's archives. Tradition has it that the order upheld the "Dromgoole legend and the ideals of Arthurian knighthood and chivalry". From all accounts, the order is social and has no clandestine agenda. Membership is closed and information about the order is strictly confidential, as is access to archives that are less than 50 years old. The Order of the Gorgon's Head, another secret society at the University of North Carolina at Chapel Hill, was founded in 1896 by Darius Eatman, Edward Kidder Graham, Ralph Henry Graves, Samuel Selden Lamb, Richard Henry Lewis, Jr., and Percy DePonceau Whitaker.

Officers include Princeps (chief officer), Quaestor, and Scriptor. The purpose of the Order is to promote friendship, goodwill, and social fellowship among its members. The Order of the Gorgon's Head was one of two "junior orders" established at the university in the 1890s. The two orders had written agreements that they would not attempt to recruit freshmen or sophomores. Each order had a lodge (the Gimghouls later built a castle), where members gathered for meetings and events. Each had secret rituals based on myths. Those of the Order of the Gorgon's Head centered on the myth of the Gorgons, three monstrous sisters prominent in ancient Greek and Roman lore. The university's library also contains the archives of the Dialectic and Philanthropic Societies. The Societies were founded in 1795 by some of the first students to attend the university, and are the oldest public school societies in the nation. While at first maintaining strict secrecy in their proceedings, the Societies' meetings are now generally open to the public; however, the
