The Ark is a building on the East Campus of Duke University in Durham, North Carolina. It serves as an instructional and rehearsal studio for the Duke Dance Program. Built in 1898 as Angier B. Duke Gymnasium, The Ark became the first home for the Duke Blue Devils men's basketball team, then known as Trinity College, in 1906. The team moved after the 1923 season, upon the completion of Alumni Memorial Gymnasium. The Ark's current name is derived from the narrow walkway that was originally used to reach the building, forcing people to enter "two-by-two".
