It began as an honor to recognize the Swedish culture and heritage of the town's early beginnings in the late 19th and early 20th centuries. A parade, a maypole dance, and traditional Swedish cuisine highlight the event.[6] [7] The celebration first began in 1978, replacing an annual Strawberry Festival held in the town.
Swede Hall, built in 1939, replaced an original hall built in 1911 at nearby Independence Valley.[8] [9] Constructed in a style similar to traditional Swedish halls, the building received approximately $200,000 during the Washington state budget in 2019 to make necessary improvements to the 80 year-old hall's infrastructure.[10]
