Main House
Main House was built in 1865, designed by James Renwick, Jr. Now a National Historic Monument, this residence hall was originally the only building of the college. It was built to accommodate both academic and residential life, heated by a boiler and gas house 400 feet behind it. The library was on the third floor and the art gallery was on the fourth floor. Even though there are eight more residence halls on campus, many more academic buildings, and a separate dining hall, all students pass through Main Building at least once a day. The first two floors of the building are now administrative offices for the Office of the President, Residential Life, Dean of Studies, Registrar and many others. It still remains the hub of activity at Vassar College. Its current capacity is 351 students.
