Constitution and Flag Day commemorates the adoption of the Swedish constitution on June 6, 1809, and the ascension of Gustavus I to the throne on June 6, 1523. It is observed throughout Sweden with patriotic meetings, parades, and the raising of flags. In Stockholm, the main celebration takes place at the Stadium, where the Swedish national anthem is sung by a chorus of several thousand voices, and the King awards flags to various schools, sports clubs, and other organizations. In the evening, the celebration continues at Skansen, the oldest open-air museum in Europe. Discuss
