Vaxholm Citadel is in Stockholm's archipelago. From Gustav Vasa's time up to the First World War, the citadel was part of Sweden's defences. However, its importance for Sweden's defence has varied somewhat.
After Gustav Vasa made Stockholm the centre of Sweden, Vaxholm gained great strategic significance. However, during the days when Sweden was a great power, the fortress lost its military significance. When those days were over, at the start of the eighteenth century, and particularly when Finland became Russian in the early nineteenth century, Vaxholm's strategic significance increased again. A major rebuild was decided upon, and this resulted in the citadel's present-day appearance.
Today the citadel houses Vaxholm Fortress Museum. The museum uses modern technology and models to depict five hundred years of the fortress and defence of the archipelago. There is also a restaurant and adventure activities.
