This Small Flag Signals That Sweden Is at Peace

These days Sweden is a peaceful nation, but it’s had a turbulent past with its neighboring countries of Norway, Denmark, and Poland. During periods of fighting it was necessary to alert the Swedish people about the state of the country. This is where the Kastellet citadel comes in.

This small naval fort is located on top of a hill on the small island of Kastellholmen just outside of the old Stockholm city center. Its most distinguishing feature is a forked Swedish flag, flying majestically above the citadel. This flag signifies whether or not the country is at peace. When it’s up all is well in Sweden. But if it’s down or replaced by another country’s flag, that means trouble.
