NRG Astrodome

The NRG Astrodome, formerly and 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, with a record attendance of 68,266 set by George Strait in 2001.

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 from 1965 until 1999, and the home to the Houston Oilers of the American Football League/National Football League from 1968 until 1996, and also the part-time home of the Houston Rockets of the National Basketball Association from 1971 until 1975.
