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 shops, restaurants, 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 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 historic three-story buildings. The commercial district surrounding the Courthouse Square was listed on the National Register of Historic Places and the Delphi Courthouse Square Historic District. 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 1840s to the 1870s. The Delphi Main Street Association encourages downtown property owners to maintain and enhance their buildings through a popular Facade Improvement Grant program.
The Wabash & Erie Canal Park and Interpretive Center celebrate the role that the Canal played in opening Indiana and the West to settlement and the ensuing economic development. Another attraction is the Delphi Opera House which is being renovated by the Delphi Preservation Society.
