It is mostly residential and includes Illinois College and the Illinois School for the Deaf.","why_significant":"The nomination argues the district is of major significance for its architecture alone, with excellent examples of nearly every major style popular in Illinois from about 1830 to the Great Depression. It also has strong historical ties to two pioneering state institutions, Illinois College and the Illinois School for the Deaf, and to figures such as Joseph Duncan and Newton Bateman.","narrative":"Covering most of Jacksonville's west side, this historic district of roughly 284 acres holds 696 structures, most of them large single-family homes on tree-shaded, park-like streets. Illinois College and the Illinois School for the Deaf anchor the area. Almost every architectural style popular in Illinois from about 1830 to the mid-1930s appears here, from the late Federal Beecher Hall of 1829 to Prairie School houses by Spencer and Powers, with Italianate and Queen Anne buildings the most numerous. The area was largely open prairie when Illinois College was founded in 1829 and the School for the Deaf was established in 1839. Those institutions drew the city's prominent residents and shaped the neighborhood's character by 1878. Notable figures linked to the area include Joseph Duncan and Newton Bateman. Only a small share of buildings are recent or intrusive, so the district remains a nearly intact section of a 19th-century Illinois city.","period_of_significance":null,"architect_builder":"Spencer and Powers (architects of the Prairie School houses, including the W.
