Houston's Astrodome was nicknamed the "eighth wonder of the world" when it opened 53 years ago in April 1965. It was the first of its kind: a massive air-conditioned stadium with a roof. The famous venue is about to be renovated and turned into an event center, but fans can get one last look inside during a "domecoming" event on Monday, April 9. Here's a look back at some memorable events the Astrodome once hosted.
