History

Six Flags St. Louis, originally known as Six Flags Over Mid-America, is an amusement park located in Eureka, Missouri, a city located within the Greater St. Louis area. The park opened in 1971 as the third theme park of the Six Flags chain and was the last park built under the Six Flags name, and remains the only park completely owned and operated by Six Flags.

The park opened with six themed sections—Spain, France, England, the United States, Illinois, and Missouri, representing the "Six Flags" for the park.
