Seattle’s Space Needle adds world’s first revolving glass floor
The renovated Space Needle, 184-m (605-ft) tall, multilevel tower in Seattle, Oregon, features the world’s first revolving glass floor. Thanks to a $100-million private investment, the interiors of the 1962 World’s Fair structure have been completely reimagined. With 196 percent more glass than before, including the use of 10 varieties, designers have created an immersive adventure.
