KNOXVILLE, Tenn. (WATE) — The Sunsphere was built for the 1982 World’s Fair and stands 26 stories tall.

According to Visit Knoxville, each pane of glass on the sphere is made with 24-karat gold which gives it its reflective gold color. There is also an observation deck, which offers a 360-degree view of the city below. Currently, the city is using the Sunsphere Fund to add enhancements to the deck.
