The Astros were born in 1962 as the Colt .45s, and the city of Houston was glad to have them. Watching games at Colt Stadium, though, was like sitting in a sauna. During the heart of the summer, game-time temperatures in the upper nineties were not unusual.
When co-owner Roy Hofheinz visited the Roman Colosseum, he learned it used to have an awning, called a velarium, to shield the audience from the sun. As a result, he financed and developed the creation of the Astrodome, the first domed sports stadium in the world.
