The emblem is often used as a symbol of official State authority by the Monarchy, the Riksdag, the Government of Sweden and by Swedish embassies around the world, but also appears in other less formal contexts, such as the Sweden men's national ice hockey team, who wear the symbol on their sweaters and hence are called "Three Crowns", and atop the Stockholm City Hall (built 1911–1923). The Three Crowns are also used as the roundel on military aircraft of the Swedish Air Force and as a sign on Swedish military equipment in general, and also on the uniforms and vehicles of the Swedish Police Authority.
