The county seat, Decatur, is a picturesque, historic city full of friendly Hoosier people. The pleasant mixture of newer homes, well-maintained older homes, tree-lined streets, and gardens reflects pride of ownership and a sense of community. The natural beauty of the St. Marys River is part of what makes Decatur a great place to live, work, and raise a family. A city of rich heritage, Decatur was the birthplace and boyhood home of David Smith, widely heralded as the greatest American sculptor of the 20th century. Decatur is also the hometown of preeminent American sculptor Ralph Hurst. Two of his works are featured in the town’s popular Sculpture Tour.


In the southernmost part of the county, Geneva was the home of one of Indiana’s most famous female authors, Gene (Geneva) Stratton-Porter. Her historic home, the Limberlost Cabin, is now an Indiana State Historic Site and is open to the public.
