Sky View Observatory at Columbia Center, Seattle

It?s hard to miss Columbia Center. Completed in 1985, the structure demands to be noticed?its three massive, interlocked concave facades stretch to a mighty 943 feet, making it the tallest building in Seattle and the 20th tallest building in the United States. The landmark occupies an entire city block, just like the Great Pyramid of Giza, and houses offices and a public [observatory](http://hstrial-cacrealestateman.intuitwebsites.com/SkyView.html) that treats eyes to views of the surrounding mountains and Puget Sound, where food and drinks are available for purchase. Inside, the behemoth building contains a panoramic 360 degree view, and the Columbia Tower Club, a private business and fine dining club located on the 76th floor.
