More on the world’s first rotating glass floor

When the Space Needle opened at the Seattle World’s Fair in 1962, it featured a rotating restaurant on the 500-foot level, just below the Observation Deck, that operated on a turntable powered first by a 1-horsepower and, later, a 1.5-horsepower motor. Inspired by the (non-rotating) glass floor the Eiffel Tower opened in 2014 on its first floor, 187 feet above the ground, and by the glass floors at Chicago’s Willis Tower and the Grand Canyon Skywalk, the rotating glass floor at the Space Needle offers visitors a view down at the fountain, the green spaces and museums on the 74-acre Seattle Center grounds.
