Tell City is a city in Troy Township, Perry County, Indiana, along the Ohio River, Indiana's southern border. The population was 7,272 at the 2010 census. The city is the county seat of Perry County. Tell City traces its 150+ year old roots to a meeting in Cincinnati, Ohio, in November 1856. A group of Swiss-German immigrants met there to organize a society known as the "Swiss Colonization Society." Its purpose was to obtain affordable homesteads for mechanics, shopkeepers, factory workers and small farmers in a location where all could live in harmony.
