V. Hill, a prominent attorney and developer. It also illustrates the Italianate style through its squarish block, low hip roof, paired consoles and ornamental lintels. The Illinois Historic Structures Survey ranked it among the three finest Italianate residences remaining in Montgomery County.","narrative":"Standing near the intersection of two state highways in Hillsboro, this two-story brick house with a low hip roof is an example of Italianate design. It has a squarish L-shaped block, paired wooden consoles under narrow eaves, tall segmental-arched windows with decorated cast iron lintels, and a front veranda with incised ornament. Art glass tops both front entrances. Inside, the original walnut staircase and three fireplaces survive. The house was probably built around 1850, replacing a small frame house on the site. John Hayward, who arrived in Hillsboro in 1834 and helped found the Hillsboro Academy, lived here. Attorney L. V. Hill, who backed the Hillsboro Electric Railway Company and helped annex and subdivide neighborhoods, bought the house in 1904, and his family kept it until 1967. Later changes included the removal of a rear dependency and the iron fence, new porches, and apartment conversion in the 1960s. A state survey ranked it among the three finest Italianate homes in the county.","period_of_significance":null,"architect_builder":"Unknown","architectural_style":"Italianate","criteria":[],"status_note":"Listed as occupied, in good condition and used as a private residence; it was divided into apartments in the 1960s, and the original walnut staircase and three fireplaces remain.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.594372-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/61/8937/28893761/content/electronic-records/rg-079/NPS_IL/80001399.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80001399/48ed7b487a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80001399/48ed7b487a-1600.webp","licence":"CC BY-SA 3.0","author":"Boscophotos","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Image_The_Hayward-Hill_House.jpeg\" rel=\"noopener\">Boscophotos</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Image_The_Hayward-Hill_House.jpeg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28893761","wikipedia":"https://en.wikipedia.org/wiki/Hayward%E2%80%93Hill_House","wikidata":"https://www.wikidata.org/wiki/Q17300100"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/montgomery-county/hayward-hill-house-80001399/"}
