Six Flags Over Texas is a 212-acre (86 ha) theme park located in Arlington, Texas, east of Fort Worth and about 15 miles (24 km) west of Dallas. It was the first Six Flags Theme Park, but because of later acquisitions it is not the oldest park of the Six Flags chain. The park opened on August 5, 1961, following just a year of construction and an initial investment of US$10 million by real estate developer Angus G. Wynne, Jr. Since its opening, Six Flags Over Texas has consistently performed well in terms of attendance and revenue, despite its history of ever-changing owners and expansions. The park currently has several amusement rides and attractions, bringing in thousands of visitors daily.
The park is managed, but not owned, by the Six Flags corporation, in an arrangement similar to that for Six Flags Over Georgia. Six Flags Over Texas is owned by a group of approximately 120 limited partners—some the heirs of Angus G. Wynne. Starting in 1991, the park was managed by Time Warner Entertainment. In 1998, Time Warner sold its interests in the Six Flags parks to Premier Parks of Oklahoma City, which later changed its name to Six Flags Theme Parks, Inc.
