Vassar College Observatory, Astronomical observatory at Vassar College in Poughkeepsie, United States.
The stone observatory building stands at the eastern edge of Vassar College campus, featuring a large central dome and residential apartments.
Built in 1865 as the first structure on Vassar College campus, the observatory gained National Historic Landmark status in 1991 for its scientific contributions.
Maria Mitchell, the first professional female astronomer in the United States, directed the observatory from 1865 to 1888, establishing women's leadership.
The original building now functions as office space, while astronomical observations take place at the modern Class of '51 Observatory on campus.
Five massive stone piers support the structure's foundation, specifically designed to eliminate vibrations that could affect telescope observations.
