223 Taylor Ave N, Seattle, WA 98109, USA- Spaces for 300-600 Guests
The Space Needle is one of the most recognizable landmarks in the world and is a treasured Seattle icon. Built for the 1962 World’s Fair—the Century 21 Exposition whose theme was “The Age of Space”—the tower’s futuristic design was inspired by the idea that the fair needed a structure to symbolize humanity’s Space Age aspirations. Since its grand opening on April 21, 1962, the landmark continues to symbolize the innovative and forward-thinking spirit of Seattle. Located at Seattle Center, the Space Needle stands at 605’ tall and is one of the most photographed structures in the world. The tower’s 520’ saucer-shaped “top house” offers visitors Seattle’s only 360-degree indoor and outdoor panoramic views of downtown, Mount Rainier, Puget Sound, and the Cascades and Olympic mountain ranges. To further elevate the visitor experience, the Space Needle embarked on a multi-year venture focused on the preservation and renovation of the 57-year-old icon. The first phase of the renovation, completed in late summer 2018, includes breathtaking, multi-level, floor-to-ceiling glass viewing experiences including an upper level outdoor observation deck with open-air glass walls and Skyriser glass benches. The Oculus, a grand wood, steel, and glass staircase connects the upper-level to The Loupe, the world’s first, and only, rotating glass floor below. The new glass floor experience opened up a never-before-seen downward view of the structure and the surrounding area, putting Seattle, literally, at your feet. Visit the renovation page to learn more about how the Space Needle is further enhancing its visitor experience. The Space Needle is proud to support local organizations who make a positive difference in the Puget Sound region through its community giving and engagement programs. Visit the Space Needle Foundation page to learn more about the Space Needle’s community giving and guidelines.
