NRG Arena

The Shell and Pennzoil Grand Prix of Houston Presented by the Greater Houston Honda Dealers was an annual auto race on the IndyCar Series circuit. It was held in a street circuit located in downtown Houston for four years, then returned after a four-year hiatus for two years on a course laid out in the parking lot of the Reliant/NRG Park complex. Before resuming in 2013, the last race was held on April 22, 2007, (with the IRL merger canceling the 2008 event just two months prior to the event).

NRG Park, formerly Reliant Park and Astrodomain, is a complex in Houston, named after the energy company NRG Energy. It is located on Kirby Drive at the South Loop West Freeway (I-610). This complex of buildings encompasses 350 acres (1.4 km2) of land and consists of four venues: NRG Stadium, NRG Center, NRG Arena and the NRG Astrodome. The complex hosts many sporting events and conventions each year, the largest of which are Houston Texans home games, and the Houston Livestock Show and Rodeo. The complex is served by the Stadium Park / Astrodome station, a light rail station on the Red Line of the METRORail light rail system. It also includes one of the world's largest parking lots (holding 26,000 total) and sees nearly 750 events yearly. Until 2005, the lot also served as a parking lot for Six Flags Astroworld, which has since closed. Since 2018, it served as the site of the Astroworld Festival, an annual music festival run by Travis Scott, which became the site of a deadly crowd crush in 2021.

The NRG Astrodome, also known as the Houston Astrodome or simply the Astrodome, is the world's first multi-purpose, domed sports stadium, located in Houston, Texas, United States. It was financed and assisted in development by Roy Hofheinz, mayor of Houston and known for pioneering modern stadiums. Construction on the stadium began in 1963, more than a year after the ceremonial groundbreaking, and it officially opened in 1965. It served as home to the Houston Astros of Major League Baseball (MLB) from 1965 until 1999, and the home to the Houston Oilers of the American Football League (AFL)/National Football League (NFL) from 1968 until 1996, and also the part-time home of the Houston Rockets of the National Basketball Association (NBA) from 1971 until 1975. Additionally, the Astrodome was the primary venue of the Houston Livestock Show and Rodeo from 1966 until 2002. When opened, it was named the Harris County Domed Stadium and was nicknamed the "Eighth Wonder of the World". After the original natural grass playing surface died, the Astrodome became the first major sports venue to install artificial turf in 1966, which became known as AstroTurf. In another technological first, the Astrodome featured the "Astrolite", which was the first animated scoreboard. The stadium was renovated in 1988–1989, expanding seating and altering many original features. By the 1990s, the Astrodome was becoming obsolete. Unable to secure a new stadium, Oilers owner Bud Adams moved the team to Tennessee after 1996, and became the Tennessee Titans in 1999. The Astros played at the dome through 1999, then relocated to Enron Field (now Minute Maid Park) in 2000. The Houston Livestock Show and Rodeo continued to be held at the Astrodome until the opening of the adjacent NRG Stadium in 2002 (which coincided with the debut of the Houston Texans, the team that replaced the Oilers). Although the Astrodome no longer had any primary tenants, it regularly hosted events during the early 2000s. It was used as a shelter for residents of New Orleans affected by Hurricane Katrina in 2005. The Astrodome was declared non-compliant with fire code by the Houston Fire Department in 2008 and parts of it were demolished in 2013 after several years of disuse. In 2014, it was listed on the National Register of Historic Places.

Serpent was a steel roller coaster at Six Flags AstroWorld. It was built by Arrow Dynamics in 1969, which made it the park's first roller coaster and the last junior mine train made by Arrow Dynamics. After AstroWorld closed at the end of the 2005 operating season on October 30, 2005, the ride was demolished.

Viper was a steel roller coaster located at Six Flags AstroWorld in Houston, Texas. Manufactured by Anton Schwarzkopf, the Looping Star model opened in 1989. It consisted of a single loop and was demolished with the closing of Six Flags AstroWorld on October 30, 2005. It had previously operated at Six Flags St. Louis, where it was known as Jet Scream from 1981 to 1988. An identical installation known as Silver Bullet still operates at Frontier City in Oklahoma City, Oklahoma. Its paint scheme is different and the tunnel on the Silver Bullet surrounds the final turn as opposed to the drop hill.

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. The Hofheinz family sold AstroWorld to Six Flags in 1978. Notable rides featured at the park included the Texas Cyclone, a wooden roller coaster built in 1976 that was modeled after the well-known Coney Island Cyclone, and Thunder River, considered the world's first successful river rapids ride when it opened in 1980. WaterWorld, an adjacent water park, was acquired and added to AstroWorld in 2002. Following declining revenue, rising property value, and other issues facing Six Flags, the company closed AstroWorld permanently after its final day of operations on October 30, 2005, the final night of Fright Fest. Many rides were sold at auction or relocated to other Six Flags' properties, and demolition of the remaining structures was completed by mid-2006.

Southern Star Amphitheatre was an amphitheatre located at AstroWorld in Houston, Texas. It opened in the southeast corner of the theme park in 1985. The venue was frequented by notable performers including The Beach Boys and Kansas. Prior to the Southern Star opening, concerts were held in the same area on a flat field with the stage at the east end. The Southern Star saw a decline in the number of top-billed acts when the Cynthia Woods Mitchell Pavilion opened in 1990. Reserved seating was available and a grassy lawn was provided to guests with general admission. The venue closed along with the theme park in 2005.
