The City of Delphi is the county seat and only city in Carroll County. Delphi is home to the Delphi Community School Corporation, a large network of parks and trails, numerous businesses, and the new replica canal boat on the Wabash & Erie Canal. In Delphi's earliest days, it was known for its large pork-packing business, and now the it hosts the county's largest employer Indiana Packers Corporation, just south of the city.
Delphi's history has been greatly influenced by various forms of transportation. It is on the Wabash River and Deer Creek--both important waterways. The first state highway from from Terre Haute to Fort Wayne was routed through Delphi in 1828. Stagecoach and mail routes came through Delphi. The Wabash & Erie Canal also had a big influence on all aspects of life in Delphi. The Canal Era ended with the arrival of the railroads. Later on the electric Interurban rail service connected Delphi to points east and west.
Delphi's downtown has many three-story historic business buildings, including some on the National Register of Historic Places. Residential areas also include many fine historic homes. Both business and residential architecture and contstuction were influenced by the relative wealth during the Canal era from the 1830s to the 1870s. Delphi Main Street encourages downtown business to maintain and enhance their buildings through a popular Facade Grant program.
