When it comes to conventions and events in the San Antonio, Texas area, only the Alamodome should come to mind.
The dome itself features all of the benefits of a dome and convention center while priding itself on having none of the drawbacks. A small amount of columns supporting the structure means that guests will always have a perfect view.
The facility is considered not only the cutting edge of engineering technology, but also a third-generation of dome architecture. From curtain wall systems to the unobstructed viewings provided by the column free spans, this is one impressive complex.
