Bumbershoot is an annual international music an arts festival held in Seattle, Washington. One of North America's largest such festivals, it takes place every Labor Day weekend at the 74-acre (299,000 m²) Seattle Center, which was built for the 1962 World's Fair. Seattle Center includes indoor theaters, outdoor stages, McCaw Hall, and Memorial Stadium. The name of the festival was taken from bumbershoot, a colloquial term for umbrella, probably coined in the 19th century as a portmanteau of umbrella and parachute.
