Shelby County is a prosperous west-central Ohio county centered on Sidney — a city with an elegant downtown characterized by Romanesque Revival architecture, including a stunning historic courthouse. The county has one of Ohio's most robust small-city manufacturing economies. Major employers include Honda of America Mfg. (the massive Anna Engine Plant is in this county, employing thousands and producing Honda engines for vehicles assembled across North America), Emerson Electric (Copeland Compressor division), and Wilson Health. The county is known for its German and Swiss heritage communities and strong Catholic and Lutheran traditions. The Piqua-Caldwell Historic District and the charming Lockington Reserve provide historical and recreational interest. Shelby County's economic strength, largely driven by Honda's supply chain ecosystem, makes it one of the most economically dynamic small counties in the state.
