Built for the 1982 World’s Fair (one of the last successful World’s Fairs), this iconic feature of the Knoxville skyline is the only structure of its kind. It is one of only two remaining structures from the historic 1982 World's Fair. It’s home to event rental space and local businesses on the upper floors, as well as the 4th Floor Observation Deck which was recently remodeled and serves as a satellite visitors center. The Observation Deck features a gallery of Knoxville images, as well as information on Knoxville and the World’s Fair and offers a breathtaking 360-degree view of Knoxville. The Observation Deck is open free to the public daily.
