O'Fallon Fact: With distinctive features that include a platoon of bronze boots and an eternal flame, no other monument in the United States is quite like O'Fallon's Veterans Memorial Walk, which was dedicated in 2001 as a place to honor all U.S. soldiers, past and present. Each year, thousands of people visit the Walk, which is free and open to the public 24/7.
