Welcome to the O’Fallon Historical Society in O’Fallon, Missouri! Founded in 1974, it is our mission to preserve and promote the O’Fallon’s history for future generations.  We operate the Log Cabin Museum in Civic Park.  The museum is a log cabin structure that was originally built in the mid 1800’s and is open the second and fourth Sundays of the month, May to September.  It features exhibits on the history of our community and shows what life was like in the area during the 1800’s. Click on “Museum” above for more information.

Nicolas Krekel

The first settlers of European descent, the Zumwalt’s,  arrived in the area in the late 1700’s and the region has a deep Native American history.  The town O’Fallon was founded in 1856 by Nicolas Krekel and his brother Arnold. They named the town for St. Louis railroad man John O’Fallon, and the railroad was vital to O’Fallon’s early success.  To learn more about the history of O’Fallon, please check out our “History” page above.

The Society meets quarterly on the first Monday of March, June, September (second Monday due to Labor Day), and December at the Log Cabin.  Everyone is welcome! Whether you have lived in O’Fallon your whole life or are new to the area, we will be glad to have you visit or join.  Annual dues are only $10 per person or $15 for couples.
