January 3, 1962, Houston
A groundbreaking ceremony is held for the "World's First Air Conditioned Domed Stadium." The groundbreaking is as unique as the building would be: in place of shovels, Colt .45s are fired into the ground. Houston's expansion team was known as the Colt .45s from 1962 to 1964.
The venue opens as in 1965 as the Harris County Domed Stadium and is soon renamed the Houston Astrodome.
The "Eighth Wonder of the World" becomes home to baseball's Astros (1965-99), football's Oilers (1968-96), the NBA's Rockets (1971-75), University of Houston football (1965-97) along with several other football and soccer teams. Other events include 1973's Battle of the Sexes and the 1989 NBA All-Star Game.
