Built in 1965 and once home to the Houston Astros and the Houston Oilers, the Reliant Astrodome is now part of Reliant Park and sits next to the new Reliant Stadium (to the left, still under construction in this photo), the Reliant Arena (that triangular thing below the Astrodome), and the Reliant Center (North of the Astrodome). The Astrodome is also famous for Astroturf, the artificial grass first used in the stadium and now found almost everywhere.
