O'Fallon History

In the 1830s a large number of German settlers arrived in the O'Fallon region. In 1854 Judge Krekel gave permission to the North Missouri Railroad to construct a train depot on his land. Judge Krekel gave the name O'Fallon Station to the depot in tribute to John O'Fallon, the railroads's president. In 1856 the first house and store were constructed.

In order to protect homes and businesses during the Civil War, German immigrants created a Union regiment to protect the vital North Missouri Railroad line. For a long span of time O'Fallon was a small town, however beginning in the early 1980's it experienced a significant population growth.
