Vaxholm Fortress
Vaxholm Municipality, Sweden · built 1544
Vaxholm Fortress (Swedish: Vaxholms fästning), also known as Vaxholm Castle, is a historic fortification on the island of Vaxholmen in the Stockholm archipelago just east of the Swedish town of Vaxholm. It is home to the Vaxholm Fortress Museum. The fortress is accessed by the Kastellet ferry, an electrically powered cable ferry across the channel from Vaxholm town. In 1970, the fortress was used as a movie location for the pirate stronghold in Pippi in the South Seas. A scenic view of the fortress may be seen from the car ferry, which plies the short distance between Vaxholm and the island of Rindö.
