O'Fallon in 1938

O'Fallon was founded in 1854. It was named after Colonel John O'Fallon, a rich man from St. Louis. A Baltimore and Ohio Railroad train station was built in downtown O'Fallon. This helped the city grow and become known.

Land was divided into lots and sold on May 18, 1854. A post office opened the next year. Many German settlers came to O'Fallon looking for good farming land. On January 27, 1874, O'Fallon officially became a village. Later, on March 14, 1905, citizens voted for it to become a city. Since it was founded, O'Fallon's population has grown in almost every census year. Only in 1930 did it lose a few residents.

The city center is about two miles east of Interstate 64 and U.S. Route 50. O'Fallon grew a lot during the 1980s. It grew even more after Interstate 64 was expanded in the 1990s. Many new neighborhoods were built, like Thornbury Hill and Fairwood Hills. O'Fallon Township High School has also added many buildings. This helps make sure there is enough space for all the students.

City Seal and Flag

O'Fallon's city seal was created in 1974. A freshman from OTHS, Michael Donovan, designed it. He won a contest held by a local club. In May 1975, the design was made final and became the city's official flag.

The design uses yellow-gold and blue colors. These are the colors of the high school. The pick and shovel on the seal show the coal mines. These mines were very important to O'Fallon's economy for over 100 years. The train represents the railroad, which helped O'Fallon start and grow. The planes stand for Scott Air Force Base. Many people in O'Fallon work there, both military and civilians.
