We're having a big birthday in 2006, our 150th, otherwise known as a sesquicentennial.  During the 1956 O'Fallon centennial celebration more than half our citizens turned out, and more than three times our population at that time attended and took part in a very big weekend.

    Now a community of nearly 70,000 people, new and old residents alike have an opportunity to share O'Fallon's history, present and future.
