Delphi is a small county seat on Deer Creek in central Indiana, about 100 kilometres northwest of Indianapolis. Named for the Greek oracle, the town has a population of around 3,000 and serves as the quiet hub of Carroll County.
The main attraction is the Carroll County Courthouse, a handsome three-storey limestone building with a stained-glass dome and a multi-level rotunda that is worth stepping inside to see. The historical society museum in the courthouse basement has local artefacts and a genealogical library. The surrounding Courthouse Square Historic District preserves much of late-19th-century downtown.
Delphi was once an important port on the Wabash and Erie Canal, and a restored section with a working replica boat and a small interpretive centre on the northern edge of town makes for a pleasant half-day. The Wabash River runs just north of town, and the surrounding farmland is quintessential Indiana prairie.
