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.[1][2][3]
