LaHarpe Historic District
Why it's listed
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.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
