The Tower stands as an 80-ton reminder of HemisFair 1968, Texas’ World’s Fair, for which it was the theme structure. The Tower is a triumphant feat of architectural and engineering skills and is still one of the tallest freestanding structures in the Western Hemisphere. Rising 750 feet to the top of the antenna, the Tower is 87 feet higher than the Seattle Space Needle, 67 feet higher than the Washington Monument. The observation deck is encircled by an outdoor walkway.
