History of The Sunsphere:
• Designed by the architecture firm Community Tectonics as the theme structure for the 1982 World’s Fair, the Sunsphere is noted for its unique design in several engineering publications.
• Each pane of glass is made with 24-karat gold giving the Sphere its reflective gold color and each pane cost around $1,000 at the time of construction.
• During the time of the World’s Fair, the tower color was blue to represent the color of the sky. The current color of the tower is forest green.
• The Sunsphere and Tennessee Amphitheatre are the only structures that remain from the World’s Fair. NOTE: The Foundry on the Fair Site, built in 1865, was originally operated as a foundry for the casting of railroad spikes and flathead nails from cannonballs. The building fell into disuse, burned, and was later renovated to host the Strohaus throughout the 1982 World’s Fair. The Foundry was purchased in 1993 and reopened to host catered weddings and events.
