Lebanon Commercial District
Why it's listed
Lebanon's downtown commercial district covers about 12 acres at the crossing of Broadway and Main Street, in the town plat laid out in 1802. Roughly fifty two- and three-story brick buildings, many sharing party walls, line the sidewalks, with larger structures marking the corners. The Golden Lamb inn, first built in 1815, and the spire-topped City Hall of 1934 anchor the district. Italianate storefronts from the 1850s to 1880s are the most common type, joined by the 1906 Carnegie Library, the 1913 Georgian Revival Harmon Hall, the 1910 Citizens National Bank and a 1937 post office. The district matters because it served as the commercial, entertainment and institutional center of a county seat and stagecoach stop, with newspapers, printing, inns, livery stables and professional offices. Its turn-of-the-century scale and appearance remain largely intact, even though surrounding areas have been altered by demolition and surface parking.
Significance in brief: The district was the focus of Lebanon's commercial, entertainment and institutional life through the nineteenth century and after. Architecturally, it keeps its original look of a compact area of low brick buildings, with the most prominent buildings on the corners. Italianate commercial buildings predominate, alongside Classical and Colonial Revival civic buildings.

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).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
