This is four venues in one, all with a slightly different focus. The Houston Texans play at Reliant Stadium, and it’s also host to the Houston Livestock Show and Rodeo. The Reliant Center is a convention center with a special market for trade shows. The Reliant Arena no longer hosts much in the way of sports (aside from the occasional wrestling), but does provide space for live events. The Reliant Astrodome was the first massive domed structure to daringly opt out on a supporting central pillar. (It’s quite sturdy.) Little happens there today, though.
