Fortification line of Vaxholm

The Vaxholm fortification line is a defense system spread across multiple islands in the Stockholm archipelago. The network consists of various battery positions and military structures positioned to guard the waterways and coastal approaches.

The system was constructed in the early 1900s as Sweden sought to defend the Stockholm archipelago. It served as the primary defense line during 1914 to 1925, a period when regional maritime security was a major concern.

The fortification represents how Sweden sought to protect its coast during a period of regional tension. Walking through the site, you can observe how military construction was integrated into the island landscape.

The different sections can be reached by boat from Stockholm or through organized tours from local operators. It is best to check transport options ahead of time, as accessibility varies with the season.

One of the most notable positions is the Kronudden Battery, equipped with four large cannons and nicknamed the 'Portuguese Battery' for reasons that intrigue many visitors. This site stands out as a focal point for those curious about early 20th-century military hardware.
