Columbia Center - Seattle's tallest skyscraper with Sky View Observatory

Columbia Center, completed in 1985, is the tallest skyscraper in Seattle with 76 floors and a distinctive dark-glass, tiered profile. Its upper floors contain the Sky View Observatory, a public observation space offering panoramic views of the city and surrounding mountain ranges. The tower's modernist setback design contrasts with many older downtown buildings and dominates Seattle's skyline.
