It has 27 structures, mostly one- to three-story brick commercial buildings from the late 19th century.","why_significant":"The district is significant in commerce and social history as an example of how an agricultural service center in west central Illinois developed from the early 1850s to the Depression. Its central business district has changed little since the late 19th century. LaHarpe's residents also worked to secure rail and highway links, and the town once hosted a seminary and still has a hospital.","narrative":"LaHarpe's historic district is the town's central business district in northeast Hancock County, Illinois. It takes in the 100 blocks of East and West Main Street and South Center Street, along with the city park. Of its 27 structures, fifteen buildings and the park contribute to its character. Most are red brick commercial buildings of one to three stories, many built in the last quarter of the 19th century. Several have multiple storefronts with repeating facades, and some keep notable metal and masonry cornices. Examples include the Campbell, Yotter, Dewey and Warren buildings. The district is significant for commerce and social history between about 1852 and 1930. It shows how LaHarpe grew from a settlement founded in the 1830s into a service center for farms in the surrounding counties. The downtown has changed little since its late-19th-century peak, though many storefronts have been modernized and some upper windows filled in.","period_of_significance":"1852-1930","architect_builder":null,"architectural_style":"Mostly 19th-century brick commercial buildings, with an Italianate commercial building, a Mission style stucco gas station and a mid-19th-century frame residence","criteria":[],"status_note":"Main use remains commercial, with some second-story apartments.
