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. The park is owned by EPR Properties and operated by Enchanted Parks. Although Six Flags no longer owns the park, the park retains its current name and branding under a licensing agreement for the 2026 season.[2] After that season, the park is planned to be renamed Mid-America by Enchanted Parks.[3][4]
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 (usually late September to late October/early November) 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.[5] 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:[6]
Missouri (now 1904 World's Fair), the main entry of the park, themed after the St. Louis World's Fair of 1904.
U.S.A. (replaced by Time Warner Studios in 1995), located in the southeast of the park, with a patriotic theme, after the United States.
France (now Chouteau's Market), located to the east, adjacent to U.S.A., themed after a colonial French trading post.
Spain (replaced by DC Comics Plaza in 1997), located in the southwest of the park, with Spanish-themed architecture and restaurants.
England (now Britannia), located in the northwest of the park, themed after a village in medieval England.
Old Chicago (currently known as Illinois), located in the northeast section of the park, themed after the city of Chicago in the early 1900s.
On June 5, 1999, the 12-acre Six Flags Hurricane Harbor water park opened, adjacent to the main park. At a cost of $17 million, it was the largest single investment in Six Flags St. Louis' history.[7]
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.[8][9] According to the Six Flags 2015 Annual Report, the park now owns 323 acres of land (with 283 acres of land used for the park, plus an additional 40 acres of undeveloped land).[8]
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.[10]
Yearly attendance figures have not been released.
On March 5, 2026, the park's owner Six Flags (which had merged with Cedar Fair in 2024) announced that it would sell Six Flags St. Louis, alongside six other park properties to EPR Properties. The sale completed on April 6, 2026 making Enchanted Parks its operator.[11] It will retain its Six Flags branding for the rest of the 2026 season.[12] Under Enchanted Parks, Six Flags St. Louis will be renamed Mid-America by Enchanted Parks, a reference to the park's original name Six Flags Over Mid-America.
