Six Flags St. Louis
Six Flags St. Louis, originally known as Six Flags Over Mid-America, is an amusement park in Eureka, Missouri, a suburb of St. Louis. Owned and operated by Six Flags, it has eight themed areas with attractions, dining, and live entertainment, many themed with characters from Looney Tunes and other Warner Bros. films and TV shows, DC Comics, and, formerly, Scooby-Doo.
The park was conceived in the 1960s by Six Flags founder Angus G. Wynne as the last of the company's original three parks. It was the first one designed by the Six Flags company; the designer of the first two, architect Randall Duell, was busy designing AstroWorld at the time. The park opened on June 5, 1971.
The park has undergone many changes, including the 1990s replacement or renaming of all six of the park's original areas and the addition of two new ones.
The park, which operates from April to November, hosts various celebrations and events. Some of the most popular are Fright Fest, which runs during the Halloween season and features many Halloween decorations and haunted houses. Star Spangled Nights takes place July 4 and features fireworks displays. The park no longer operates Holiday in the Park, which ran from November to early January and featured Christmas decorations and music, New Year's fireworks, and more.
History
Opening and operation
Plans for a Six Flags park in the St. Louis area—dubbed Six Flags Over Mid-America—were announced on July 16, 1969. The park opened on June 5, 1971, the third and last of the three "true" Six Flags parks as envisioned by Angus G. Wynne. The park was divided into six themed sections: the namesake "Six Flags" over Mid-America:- Missouri, the main entry of the park, themed after the St. Louis World's Fair of 1904.
- U.S.A., located in the southeast of the park, with a patriotic theme, after the United States.
- France, located to the east, adjacent to U.S.A., themed after a colonial French trading post.
- Spain, located in the southwest of the park, with Spanish-themed architecture and restaurants.
- England, located in the northwest of the park, themed after a village in medieval England.
- Old Chicago, located in the northeast section of the park, themed after the city of Chicago in the early 1900s.
In 2014, Six Flags sold 180 acres of unused land to the east of the park to developer McBride & Sons, effectively reducing the total property area of the park from 503 acres to 323 acres. According to the Six Flags 2015 Annual Report, the park now owns 323 acres of land.
In January 2020, construction began on a renovated entry plaza, removing the original ticket booths that had been at the park since its opening in 1971. Subsequently, in March of the same year, Six Flags St. Louis announced that the opening of their 2020 season would be delayed, due to the COVID-19 pandemic.
Yearly attendance figures have not been released.
