Was the 'focal-point' of the 1982 Worlds Fair. Most of the other structures have disappeared but this iconic feature remains. You can take an elevator ride up to the observation deck for a 360-degree view of Knoxville. Stations with information describing what you are viewing...More

The ride in the elevator was a bit shaky, but worth it. The view from the observation deck was great with information along the walk. We'll have to go again in spring or summer for a different view.

Not much of a view. Some interpretive signage with area information. Windows don’t provide a very good view because of the gold coating. Don’t make a special trip, park grounds are more interesting than the dome.

Easy access with nearby parking, walkways and elevators to the observation deck. Entrance is free, with great views of K-ville and surrounding country. Nice art and information displays at observation deck. Must see in K-ville.

This is an icon of the 1972 World's Fair and is the centerpiece if the World's Fair Park. Take the free ride to the observation deck, where you have a great view of Knoxville.
