The Astrodome, the first domed sports stadium, was conceived as an escape from the subtropical weather that plagued Houston's sports enthusiasts. The complex is 18 stories tall and was originally designed to accommodate both baseball and football games. Today, the Astrodome does not host any major sports teams and has been overshadowed by its also domed neighbor, Reliant Stadium.
Fun Fact: The Astrodome housed about 25,000 Hurricane Katrina refugees from Aug. to Sept. 2005.
