Fredriksborg Fortress and the Vaxholm line for 500 years

Vaxholm has been a vital part of Stockholm's and Sweden's defense for 500 years. Fredriksborg Fortress, built in 1735, was the most advanced fortification of its time, guarding the Oxdjupet passage and complementing the Vaxholm Fortress from 1549. Together, they protected the entrances at Oxdjupet and Kodjupet until Oxdjupet was blocked, and Vaxholm Castle replaced Vaxholm Fortress in the 1800s.

Explore Fredriksborg Fortress and listen to its history narrated by Fredriksborg Hotel's guide on all open days from May to September. Special tours for groups can be arranged.

The defense system known as Vaxholm Fortress and the Vaxholm Line begins on the Värmdö side of Oxdjupet, the only deep inlet towards Stockholm.

In 1735, Fredriksborg Fortress was completed, later replaced by Oscar Fredriksborg Fort in 1877. The Myttinge Line, part of the Vaxholm Line, was constructed on the Värmdö side, concurrent with the establishment of KA1 on Rindö by the defense forces.

Fredriksborg Hotel is situated in the old officer residences of Fredriksborg Fortress from the same era, guiding visitors through Fredriksborg Fortress on all open days from May to September. The defense of Vaxholm is intertwined as a crucial part of Sweden's history since the construction of Vaxholm Fortress in 1549.

The hotel's guide will showcase the fortress's cannon platform, vaults, and powder room, concluding at a height of 60 meters in the observation tower. Originally over 6 meters taller, part of the building was dismantled to provide material for Vaxholm Castle, earning it the nickname 'butter box' in local parlance. It remains a majestic structure, occasionally used for wedding celebrations, galleries, music events, and more.

The guided tour is complimentary for hotel guests, whether staying overnight or dining for lunch or dinner. For non-guests, the tour costs 95 SEK per person (50% discount with the Swedish Cultural Heritage Card).

English tours are available upon request immediately after the Swedish tour during the summer season.
