Whitin Observatory

The Whitin Observatory is the home of the Wellesley College Astronomy Department and houses classrooms, astronomy laboratory facilities, the Astronomy Library, and faculty offices. 

Built in 1900, and enlarged in 1906, 1966, and 2010, it is considered an unusually fine facility for undergraduate training in astronomy. Read about the Whitin Observatory Construction Project: Links to the Past and a Vision for the Future. (ca. 2001, PDF file, 1 Mb; requires Acrobat Reader.)
