Myers and built in 1869-70 for George M. Brinkerhoff. It is known as The Castle and sits on the campus of Springfield College in Illinois.","why_significant":"It was the home of George M. Brinkerhoff, a prominent Springfield capitalist and civic figure. It is also one of the few surviving works from the early career of architect Elijah E. Myers, who later designed several state capitols. It remains an intact example of high style 19th century Italian Villa design.","narrative":"Built in 1869-70 and known as The Castle, this two and one half story L-shaped brick house in Springfield, Illinois, was designed by Elijah E. Myers in the Italian Villa style with Gothic revival touches. Features include brackets under overhanging eaves, brick quoins, a dentiled cornice, arched openings trimmed with Myers' signature wooden rope molding, and an original slate roof. Inside, fourteen types of hardwood, a curving walnut stairway, and marble and Eastlake mantels survive largely unchanged. George M. Brinkerhoff, a self-made banker, city comptroller and railway and iron company founder, lived here until 1928. The house then went to the newly founded Springfield Junior College, now Springfield College in Illinois, serving as dormitory, classrooms and meeting space for civic groups. Its listing rests largely on Myers, who rose from carpenter to architect in Springfield before designing state capitols, and on the house being one of few remaining examples of his work from that period.","period_of_significance":"1800-1899 (specific dates: Brinkerhoff family-1928)","architect_builder":"Elijah E.
