The Convention Center, later named after U.S. House Rep. Hon. Henry B. Gonzales, was the largest of three structures built as part of the convention center complex. It was built to address San Antonio’s growing economic and business needs after HemisFair.

One unique design feature was the two story stair lobby which features a grand mosaic mural created by Guatemalan artist Carlos Merida titled “The Confluence of Civilizations”

During HemisFair ’68

The Theme Gallery located above the river level entrance hosted an exhibit featuring several masterworks Spanish art during the six month run of HemisFair.

The main section of the building featured an exhibit named “The Cosmos”.

After the Fair /Expansions

In the 1980’s the convention center was expanded going east on Market St. behind the convention center lagoon and south along N. Alamo St.

In the mid 1990’s the HemisFair Arena was demolished to make way for another major expansion of the convention center. The center now spans the full length of Market St. from N. Alamo to IH 37. Included in this expansion was to extend the river walk further into the convention center lagoon and restored walkway access from river level into HemisFair park.
