It holds exhibition halls, barns, a grandstand, race tracks and service buildings.","why_significant":"It became the permanent home of the Illinois State Fair in 1894, and its early buildings were designed in a monumental neoclassical style inspired by the 1893 World's Columbian Exposition. The concentration of fair buildings from the 1890s to the 1930s shows how the fair grew from an agricultural showcase into agriculture plus entertainment. The form says the buildings keep good overall integrity despite window replacement.","narrative":"Illinois State Fairgrounds covers 366 acres on the north edge of Springfield, bounded by Sangamon Avenue, Peoria Road and Fifth Street. Springfield citizens donated the first 156 acres in 1894, and the city added sewers, grading and fencing while the state legislature appropriated money for buildings. The earliest structures, including the 1894 Exposition Building, the Poultry Building and a large dome building brought from the Columbian Exposition, followed a monumental neoclassical approach. Later decades added horse barns, cattle barns, a coliseum, swine and sheep pavilions, and a 1927 grandstand, while the state bought another 210 acres in 1924. The grounds are laid out for pedestrian traffic, with open spaces between buildings for temporary exhibits. Of 165 resources counted, 63 contribute to the district, and the large early buildings dominate the most public areas. Rehabilitation work has kept massing, window patterns and form largely original. The site records the fair's growth from an agricultural exhibition into a broader public event.","period_of_significance":null,"architect_builder":null,"architectural_style":"Classical Revival","criteria":[],"status_note":"Buildings are mostly in very good to excellent condition, and a major rehabilitation program of roofs, wiring and life-safety systems is continuing.
