Alamodome The Alamodome is what is known as a "third generation" facility. It features the very latest in dome architecture and engineering technology, with column-free spans for unobstructed viewing and a curtain wall system for configuration flexibility. So whatever your event, chances are the Alamodome can accommodate you. With the Alamodome you get the advantage of both a convention center and a dome without the drawbacks of either. The Alamodome is large enough to easily accommodate assemblies and tradeshows. The column-free design makes it unlike other domes in one very important way: it has an intimate, "human" scale.
