Pacific Science Center Arches
Since the 1962 Seattle World's Fair, Pacific Science Center's arches have been a familiar part of the Seattle skyline. Designed by Minoru Yamasaki, Pacific Science Center's white arches rise above a court of reflecting pools. At night, they light up the sky with their vibrant colors - green for St. Patrick's day, orange for Halloween and many more. Pacific Science Center is proud to support many local organizations and national causes by changing the color of the arches to correspond with special events and awareness months. Interested in what color the arches are right now? See the calendar below for upcoming changes and the story behind each color. Check back often as the calendar will change regularly. And don't forget - next time you're in the area, take a moment to view some of the most original architecture in Seattle.
Have an occasion or milestone coming up and want to celebrate by turning the arches a special color? Now, for the first time in more than 50 years, you can choose to light up the night; any color, any occasion. All proceeds benefit our 50 for 50th: Future Ready Campaign. Learn More.
