Mid America Adventure
amusement park operated by Enchanted Parks
Mid America Adventure, formerly known as Six Flags Over Mid-America and Six Flags St. Louis, is an amusement park in Eureka, Missouri, a suburb of St. Louis. Founded in 1971 by Six Flags, the park was purchased in 2026 by EPR Properties, which hired Enchanted Parks to operate it.
The park was conceived in the 1960s by Six Flags founder Angus G. Wynne. Unlike his company's first two parks, it was not designed by architect Randall Duell, who was busy designing AstroWorld, but by the company itself. The park opened on June 5, 1971. It has undergone many changes, including a 1990s revamp that added two new areas and replaced or renamed all six of the park's original ones.
Mid America Adventure operates from April to November. In the fall, the park hosts the Halloween-themed event Fright Fest.
This brief starts where responsible research should: with the source description of “Mid America Adventure” as amusement park operated by Enchanted Parks. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as amusement park operated by Enchanted Parks. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q261618. Authority coordinates are 38.513, -90.675. 2 of 4 selected statements include explicit references; 3 carry qualifiers and 1 use preferred rank. The first chronological checks are 1971 and 2026.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
