Six Flags AstroWorld

Six Flags AstroWorld, also known simply as AstroWorld, was a seasonally operated amusement park in Houston, Texas. Owned and operated by Six Flags, the park was situated between Kirby Drive and Fannin Street, directly south of I-610. The park opened on June 1, 1968, and was developed originally and constructed as part of the Astrodomain, the brainchild of local philanthropist and former Houston mayor Roy Hofheinz, who intended it to complement the Astrodome. Hofheinz had acquired the circus in December 1967), and four hotels with a capacity of 5,600 guests to serve visitors: the Astroworld Motor Hotel (with a private suite for Hofheinz on the ninth floor), Holiday Inn-Astroworld, Howard Johnson Motor Lodge-Astroworld, and Sheraton Inn-Astroworld.

In 1967, Hofheinz initially denied that preliminary work for an amusement park had been underway, but later announced on September 16 that approximately half of the remaining land, , was being developed for a park to be named "Astroworld". Hofheinz showed an architectural model of the park and announced that Randall Duell and Associates had designed it; Duell, a Hollywood set designer and architect, had previously designed Six Flags Over Texas. An initial $25 million investment paid for extensive landscaping and a long pedestrian viaduct spanning the I-610 freeway, the first privately owned, publicly accessible span over a federal highway. Lloyd, Morgan & Jones designed the bridge.

Additional design work for the park was performed by I. A. Naman & Associates (air conditioning); Lockwood, Andrews & Newnam (electrical); Walter P Moore (structural); Turner, Collie & Braden (civil engineering); and Linesch & Reynolds (landscape architects). Henderson's model of AstroWorld, measuring , was built as a publicity preview of the park in 1967. Architecture students at Rice University and the University of Houston sculpted many of the buildings. then moved to Hofheinz's Astrodome suite once the park opened; In 2011, it was sold to I. A. Naman and Associates, the same firm that had designed the park's outdoor air conditioning; they donated the model to the Houston Public Library. referring to the Duell loop that routes visitors through each part of the park. Two of the park's sixteen attractions were not operational on opening day.

Marvel McFey, the park's official mascot (branded the "Ambassador of Happiness"), was introduced in 1972. He was accompanied by a menagerie of "animal gypsies": Winston Wolf (the sheriff of AstroWorld); Pigs One, Two, and Three (mischievous tricksters named Quiz, Chiquito, and Harpo); Percy Penguin; Pierre Le Rat (the resident artist); Flopper Rabbit (a country bumpkin); Beethoven Bear (a checkers champion); Samantha Skunk ("a bright purple and pink flower child"); Frieda Frog (McFey's secretary); and Lester Lion (a frustrated baseball player). In addition to their in-park greeting and show duties, Marvel and his caravan of Enchanted Animals represented AstroWorld at many civic functions.

In 1970, just two years after the opening of Astroworld, Hofheinz survived a stroke that left him in a wheelchair. Those creditors assumed control of the Astrodomain in 1974. The following year, Six Flags AstroWorld introduced a new, high-speed roller coaster, the Texas Cyclone. That same year, Robert Cartmell named the Texas Cyclone the best roller coaster in the world. The formal purchase of AstroWorld by Six Flags concluded in 1978. AstroWorld's parent corporation, Six Flags, had acquired the license to use the Looney Tunes characters in 1984 for its theme parks from Marriott along with the Great America in Gurnee theme park; Marriott had held the license since 1976 for its twin Great America parks.

Six Flags continued to change ownership, being purchased by Bally Manufacturing in 1982, then by a private equity firm, Wesray Corporation, in 1987. Time Warner acquired a minority stake in 1990 and owned the company outright by September 1993. In the early 1990s, the Six Flags parks gained access to DC Comics characters through its corporate owner, Time Warner; Batman: The Escape was installed at AstroWorld for the 1993 season. In February 1998, Premier Parks, led by CEO Kieran Burke, acquired Six Flags Entertainment Corporation. In 1984, Premier, originally Tierco, a property management group, hired Gary Story to rehabilitate one of its properties, an older park named Frontier City in Oklahoma City; Story's successful turnaround of that park started the company's theme park acquisition program.

Closure and demolition

The Six Flags acquisition was part of an ambitious Premier Parks purchasing program, which bought 31 amusement parks in four years, including the 12 Six Flags parks. Burke received a $2 million bonus for completing the Six Flags acquisition. However, Six Flags failed to turn a profit for five straight years after the 1998 acquisition, announcing a $122 million loss for the first half of 2003; capital expenditures began to be scaled back because of its debt load. In August 2005, Six Flags announced it was selling its chain of parks. One month later, on September 12, Burke announced AstroWorld would be closed and demolished at the end of the 2005 season. In 1997, the combined attendance of AstroWorld and Water World was 2.27 million visitors; AstroWorld alone was ranked as the 28th most attended theme park in the United States with 1.99 million guests. AstroWorld attendance ranked 35th overall among all theme parks in 2000, 37th overall in 2002, 36th overall in 2003, and 39th overall in 2004, which was eighth among all Six Flags parks in 2004. Burke later explained in 2014 the decision was based on "[AstroWorld's] condition and location and the costs to modernize ... we had big offers pouring in for the land at the time and it just made more sense to close it." The final date of park operation was October 30, 2005.

Company executives expected to sell the land for as much as $150 million, but ultimately received less than half that amount. After spending $20 million to demolish the park and clear the land, Six Flags sold the cleared property for $77 million in 2006 to Angel/McIver Interests, a land development firm based in Conroe, Texas. By that time, Burke had been removed as CEO. In 2009, the former Astroworld site was still vacant. The land tract was reported as taking up . The land owners hired real estate consultants, Croswell Torian Commercial Properties, to subdivide and market the property to other developers under the "SouthPoint" brand, though no development had yet occurred. The original tract purchased by Hofheinz was reduced by : were acquired by Harris County Metro and another piece of the tract on the northwest corner sold to a car dealership. Though the site includes a great field of grass, the land is stabilized and partly paved with asphalt, so it can be used for parking.
