We’re heading straight into the center of the sun… sphere. We’re in Knoxville visiting the beloved centerpiece of the Marble City skyline.

Welcome to the Sunsphere. Built as the architectural focal point of the 1982 World’s Fair, this 266-foot tall structure greeted over 11-million visitors to east Tennessee as they came from around the globe to explore the Knoxville International Energy Exposition.

Energy was the focus of the fair, and so it made sense that the nucleus of the event was the sun. Each pane of glass is made with 24k gold – sparkling in the light, and dazzling visitors to this day.

26 stories up, the view dazzles just as much as the tower itself. From here you can see the Smoky Mountains, the UT campus, the Tennessee River, and the city skyline. This is a 360-degree panorama with all of Knoxville and beyond laid out before you.

In addition to the views looking out, there is also plenty to see displayed within. Here you’ll find some great information about the Sunsphere itself, and a history of the World’s Fair.

You can see how this structure was built, gaining a real appreciation for its design. And there are some fun displays with items from the exposition. And the info panels around the observation deck give great information as well.

Below in the park surrounding the Sunsphere you’ll also find the only other remaining structure from the World’s Fair, the Tennessee Amphitheater. And the park here hosts crowds once again, serving as a community gathering space for the enjoyment of all who visit.

Just over 40 years ago this place was the center of the world. Pavilions from 22 countries shared their arts, culture, and discoveries with all who attended. And today, the Sunsphere still beckons you to come and share some fun and excitement with friends and family.
