The Tower of the Americas is a 750-foot (229-meter) observation tower-restaurant located in the Hemisfair district in the southeastern portion of Downtown San Antonio, Texas, United States.

The tower was designed by San Antonio architect O'Neil Ford[1] and was built as the theme structure of the 1968 World's Fair, HemisFair '68.

[6] The Tower of the Americas was conceived as the theme structure for HemisFair '68, a world's fair held to celebrate the 250th anniversary of San Antonio.

[19] Since 1970 the roof has hosted a 30-meter-tall (98 ft) tapered steel mast, used as support for three FM antennas; 101.9 KQXT (then known as KCOR-FM), 102.7 KJXK (then KTFM), and 104.5 KZEP (then KITE-FM).

Clear Channel Radio and Electronics Research Inc. headed up the project along with their contractors and involved the City of San Antonio and Landry's Restaurants.

An option existed for several years to add facilities for a move in signal on 97.7 (requiring rearrangement of ten other stations) to share the site.
