Main Building, Poughkeepsie

The Main Building of Vassar College is the oldest surviving building on its campus in Poughkeepsie, New York, and the center of academic life. It was built by James Renwick, Jr. in the Second Empire style in 1861, the second building in the history of what was one of America's first women's colleges. It is one of the earliest, largest, and most important examples of Second Empire architecture in the United States and is a National Historic Landmark for its architecture and educational significance. At the time of its completion, the structure contained the most interior space of any building in the United States, and housed the entire college, including dormitories, libraries, classrooms, and dining halls. Currently, the first and second floors house campus administration while the remaining three house student rooms. ()
