July 4, 2026 marks the 250th anniversary, or semiquincentennial, of the adoption of the Declaration of Independence. Communities throughout America are planning large, patriotic celebrations in anticipation of this milestone. Join us for the first look at the newest exhibit that looks at the many ways people have celebrated these past anniversaries. Perhaps you remember or attended some of these celebrations! Join us for the opening reception of Parades, Picnics, and Pageants: South Dakota Celebrates on November 13th from 4:30-6:30 p.m. Admission is free. Refreshments will be served, sponsored by the Siouxland Heritage Museums Alliance.
