Originally called the Harris County Domed Stadium, the Astrodome was completed in 1964.
Conceived as the home of the Houston
Colts and Houston
Oilers, it was termed by many as the
Eighth Wonder of the World
It was the first time that a stadium was
built for both baseball and football that was
totally enclosed and fully
air-conditioned. The building covers 9.14 acres of land.
Circular in shape, the outer diameter of the Astrodome is 710' and the clear span of the dome roof is 642'.
