Welcome to Parktimes.com, covering the fifty year History of Six Flags Over Texas. The park is the first and oldest in the Six Flags theme parks' chain of amusement parks. Opening in 1961, six years after Disneyland, the park was one of a hand-full of new theme parks which opened in the last 50's and early 60's. With the exception of Disneyland and Six Flags Over Texas, the others all closed or went bankrupt within a few seasons. Six Flags Over Texas flourished and expanded, and was followed by Six Flags Over Georgia and Six Flags Over Mid-America.
