The Swedish Royal Forces day or Försvarsdagen takes place on Sun 24th September this year at Gärdet.
Activities will be held throughout the day from 11.00 am until 4.00 pm. Many of them will include vehicles and aircraft used by the Swedish Armed Forces. On the day, because of low altitude flying, and other activities, some noise will reach the surrounding area. Most exhibitions, demonstrations and displays will be held on the grass field just north of the Maritime Museum (Sjöhistoriska).
Next to the water, on the other side of Djurgårdsbrunnsvägen, you can meet the Swedish Home Guard. The sailing ship HMS Falken will be open for public viewing, next to the Vasa museum.
