Discover O'Fallon, Missouri!
Today, O'Fallon's borders have expanded to about 30 square miles with a population of nearly 83,000.
The same railroad line that started the O'Fallon is still in operation. The City of O’Fallon’s unique attractions offer something for everyone. You can swim or exercise regardless of the weather at the Renaud Spirit Center recreation complex, go picnicking in a City park, or relax in style at a River City Rascals ballgame.
If you’re a heritage tourist, O’Fallon’s important memorials and historic sites include two 9-11 monuments created from New York’s World Trade Center debris, a rare War of 1812 fort site and one of the first monuments in the country to honor those who gave their lives in the Vietnam War.
