The Buffalo and Erie County Historical Society is located on Nottingham Court in the city of Buffalo, just east of Elmwood Avenue, north of the Scajaquada Expressway, in the northwest corner of Delaware Park. It occupies the building constructed in 1901 as the New York State pavilion for that year`s Pan American Exposition, the sole surviving permanent structure from the exposition. As planned, the (then) Buffalo Historical Society moved into the building after the exposition.
