Does the Space Needle's Top Move? No—It's Fixed

The top of the Space Needle in Seattle does not move. The entire structure—including the observation deck (520 ft) and the rotating Loupe glass floor (500 ft)—is stationary.

What Does Rotate?

• The SkyCity Restaurant (formerly) rotated 360° every 47 minutes on a turntable inside the top house.
• Current: The Loupe (world's first rotating glass floor) completes a revolution every 30 minutes. Only the floor ring rotates; the outer structure, walls, and observation deck remain fixed.

Structural Stability

• Founded on a 30-ft deep, 120-ft diameter concrete ring anchored 100 ft into bedrock.
• Center of gravity is 5 ft above ground—extremely stable.
• Designed to withstand 200 mph winds and 9.0 earthquakes.

No part of the external architecture moves. The rotation is an interior experience only.
