The headquarters of the American Geographical Society were initially established at New York University in Washington Square. The University's chapel was used for some of the society's lectures and the AGS remained at this location until 1858. Later, two rooms located in Clinton Hall, formerly the Astor Opera House, became the society's next home in December 1858. In 1866, the American Geographical Society moved to Cooper Union at Cooper Square on Ninth Street, where it remained for ten years. In 1911, the AGS moved to 3755 Broadway at 156th Street. This three story building was built on land donated by Archer Milton Huntington's mother and designed by Charles Pratt Huntington. Audubon Terrace became the society's most prominent home and was visited by many scholars and dignitaries, including President Woodrow Wilson.
