The Ark - 1898 -Built and furnished in 1898 with a donation from Benjamin N. Duke, the building was officially named the Angier B. Duke Gymnasium in honor of his son who was then fourteen years old. When the more modern Alumni Memorial Gymnasium opened across campus in 1923, the original gym assumed a new identity. Over the next decade, as the building was put to a variety of uses, its long, narrow, bridge-like walkway forced people to enter "two by two;" hence, it became commonly referred to as the Ark. Now it is primarily used by the Duke Dance Program.
