Senior Rock

Though the origins of this tradition are not known, it is said that the large boulder in front of Gunn Dorm can only be touched or climbed by seniors.

• The plaque on the rock has an inscription dedicating the campus to the third Headmaster, William Hamilton Gibson, who built the quad with architect Richard Henry Dana and philanthropist Adrian Van Sinderen in the 1920s and 1930s.

• Seniors have traditionally used the rock as a place to gather, play or study and assemble there for a class photo each spring in attire representing the college or university to which they have been accepted.
