The listed property also includes a converted garage gallery and the 1865 James Mason House.","why_significant":"The nomination presents the mansion as one of the finest early twentieth-century examples of its type, noted for Italian Renaissance Revival design and richly detailed interiors. An amendment adds prehistoric archaeological significance, based on 1981-1983 excavations that found stratified deposits spanning about 8,000 B.C. to A.D. 1400.","narrative":"Built between 1904 and 1909 at 30 Front Street in Binghamton, this mansion was the residence of Alonzo Roberson and now serves as an arts and sciences center. It is a symmetrical two-and-one-half-story building in the Italian Renaissance Revival style, made of pinkish, Roman-style brick with limestone trim and a green ceramic tile roof. A semicircular portico with paired fluted columns marks the front, and tiered porches overlook the Chenango River at the rear. Inside, rooms are finished in woods such as pecan, mahogany, maple and walnut, with painted canvas ceilings and stained glass. The property also includes a converted garage gallery and the 1865 Two Rivers house, while a 1968 museum wing is noncontributing. Excavations in 1981-1983 near the parking area uncovered undisturbed prehistoric deposits, including cooking hearths, projectile points and over 65,000 artifacts spanning roughly 8,000 B.C. to A.D. 1400, so the listing was amended to recognize archaeological value.","period_of_significance":"1904-1909","architect_builder":"C.
