Imagine a football stadium that was so technologically game-changing that it became the model for all future sporting venues ever built. Until it was suddenly abandoned 15 years ago. As part of our series Preservation Battle, we look at significant buildings on the brink of demise—where you've been able to find Houston's Astrodome for quite some time.
The Astrodome was heralded as a modern marvel when it opened in 1965: it was the first enclosed football stadium on the planet. But the sports teams packed up in 1995, leaving its legendary Astroturf behind. Last year, voters turned down a $217 million bond to transform it into a convention center, but the Dome was recently listed to the National Register of Historic Places, which may provide the architectural equivalent of a Hail Mary (although it doesn't protect it completely from demolition).
