What stands out about Nininger Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The city of Nininger was founded and named by John Nininger, brother in-law of territorial and state Governor Alexander Ramsey. Nininger incorporated during the winter of 1857 or 1858. Nininger had high hopes for his namesake city to become state capital, and indeed its population did reach nearly 1,000 by the spring of 1858. The city did not flourish, however, and its post office was discontinued in 1889 after 33 years of operation. Today little trace of the original city remains, although two plaques describe Good Templars Hall and Ignatius L. Donnelly's home.
