City Facts for O’Fallon IL

O’Fallon, one of the fastest growing communities in the Greater St. Louis area, is a city rich in history and one of the area’s most popular places to live and work. Located a short 15-minute drive from downtown St. Louis, its nearly 30,000 residents include many personnel from nearby Scott Air Force Base. The former coal mining town, a sister city to O’Fallon, MO, is well-known for its mix of small-town friendliness and community pride.

Native American settlements date back centuries here, with the first modern settlement made in 1802. Early residents were attracted by the rich land that was well-suited to agriculture. In 1827, John Mason Peck established Illinois’ first college, Rock Spring Seminary in O’Fallon. Over the next 25 years, coal mines sprung up and the Ohio & Mississippi Railroad was built. The first public school was built in 1861, the Community Park was dedicated in 1924, and the public library opened in 1930.

O’Fallon residents are ideally situated to enjoy all that downtown St. Louis has to offer, but the city has several attractions and events of its own. The O’Fallon Historical Society features locally-themed exhibits and the O’Fallon Veterans’ Monument features an interactive kiosk that provides a brief history of each veteran included in the memorial. The city has eight popular parks, including Hesse Park, Rock Springs Park, and St. Ellen Mine Park with its many walking and biking paths and small fishing lake.
