O'Fallon, Illinois is one of the largest cities in the Metro-East region, and it continues to grow as a desirable suburb of St. Louis, which is only about 17 miles away. The city of O'Fallon was first put on the map with the development of the Baltimore and Ohio Railroad depot, which was shortly followed by the construction of a U.S. Post Office and incorporation of the village named for Colonel John O'Fallon. German settlers were among the first to populate the area in search of fertile farmland.

Today, O'Fallon is a popular residential community for active and retired military personnel thanks to its nearby proximity to Scott Air Force Base. The city's subdivisions are always growing as the population of the city continues to climb.
