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. We've gone red for American Heart Association and orange for Hunger Action. If the Mariners or Seahawks make the playoffs, our arches will reflect team colors. 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.
