Six Flags Over Texas is a major amusement park located in Arlington, Texas (USA), east of Fort Worth and about 15 mi (24.1 km) west of Dallas. It is 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 not owned by the Six Flags Theme Parks corporation. In an arrangement similar to that for Six Flags Over Georgia, it is owned by a group of approximately 120 limited partners-some the heirs of Angus G. Wynne-and is managed by the corporation. 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.
