Jefferson County

Jefferson County is an administrative division in southeastern Indiana featuring rolling terrain, farmland, and forested areas. The landscape slopes toward the Ohio River and combines rural landscapes with scattered settlements and towns.

The county was established in 1810 and named after President Thomas Jefferson, formed from sections of Clark and Dearborn counties in Indiana Territory. Its creation reflected the early expansion of American settlement across the region.

The courthouse in Madison displays early 19th-century architectural styles that blend federal and Greek revival elements. The building shapes the town center and shows how residents have valued their public spaces.

The main towns and communities are reached by state and county roads that run through the terrain. The region is best explored by following these roads, which connect the larger settlements to the more rural areas.

The area has a long connection to river trade on the Ohio, a waterway that has shaped commerce and movement for generations. This history remains visible in how the landscape and settlements relate to the water today.
