More about the City of O'Fallon, IL

OFallon-City-Hall

O’Fallon, IL is a city in St. Clair County, Illinois, United States. The 2010 census listed the population at 28,281. The city is the third largest city in the Metro-East region and Southern Illinois. It sits 5 miles (8.0 km) from Scott Air Force Base and 18 miles (29 km) from Downtown St Louis.

The city center is approximately two miles east of the intersection of Interstate 64 and U.S. Route 50. Suburban growth in O’Fallon expanded considerably during the 1980s and following the expansion of Interstate 64 in the 1990s.

Like its namesake in St. Charles County, Missouri, O’Fallon is part of the St. Louis Metropolitan Statistical Area. This makes O’Fallon (along with the two Troys in Illinois and Missouri) one of the few pairs of like-named municipalities to be part of the same MSA.

One of the most notable residents was William Holden (born William Franklin Beedle Jr.; April 17, 1918 in O’Fallon, IL). Holden was an American actor who was one of the biggest box-office draws of the 1950s. He won the Oscar for Best Actor for the film Stalag 17 (1953), and a Primetime Emmy Award for Outstanding Lead Actor in a Limited Series or Movie for the television film The Blue Knight (1973). Holden starred in some of Hollywood’s most popular and critically acclaimed films, including Sunset Boulevard, Sabrina, The Bridge on the River Kwai, The Wild Bunch, Picnic, and Network. He was named one of the “Top 10 Stars of the Year” six times (1954–1958, 1961), and appeared as 25th on the American Film Institute’s list of the 25 greatest male stars of Classic Hollywood Cinema.
