Question: What prominent San Antonio landmark was built for the 1968 international exhibition known as the HemisFair?
Answer: The Tower of the Americas. Designed by San Antonio architect O’Neil Ford, the 750-foot tower was the tallest observation tower in the U.S. between 1968 and 1996, when it was overtaken by the Las Vegas Stratosphere Tower. The tower contains a revolving restaurant and can be accessed via one of three elevators.
