St. Clairsville Historic District
Why it's listed
Downtown St. Clairsville, Ohio, is preserved as a historic district of 19.7 acres along Main Street, which follows the old National Road (US Route 40). Of its 84 resources, 64 contribute to its character. The core is a stretch of two- and three-story masonry commercial buildings, many rebuilt after an 1866 fire destroyed much of Main Street. The 1884 Belmont County Courthouse, designed by Columbus architect Joseph Warren Yost, dominates the center, with an adjoining jail and sheriff's residence. Commercial buildings such as the Jenkins Building, the 1894 Gazette Building, the 1889 Clarendon Hotel and the Art Deco Masonic Building show Romanesque, Italianate and other styles. Federal-style brick houses from about 1815 to 1850 line the eastern edge. The district was recognized for its role in the town's growth as a trading center linked to the National Road and for the range of architecture it preserves, despite later siding and storefront changes.
Significance in brief: The district reflects the growth of St. Clairsville as a county seat and commercial center on the National Road. Its early Federal residences, post-1866 fire commercial blocks, and the 1884 courthouse show the town's development from settlement through the early twentieth century. It also illustrates a wide range of architectural styles.

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).
