Fagersta airspace surveillance tower

During World War II, the steel mill company Fagersta Bruk AB (no longer in existence) was an important supplier of munitions and weapons for the Swedish Armed Forces.

[1] While Sweden remained directly unaffected by the war, the country maintained a high degree of military readiness.

In order to be able to defend the steel mill in the event of an attack on Sweden, anti-aircraft guns were placed by the military around strategic industrial sites.

The tower was finished in 1944, but saw no use in its intended capacity, since the war ended within a year of its construction, and the neutrality of Sweden was not violated during that time.

[1] It has been noted that the design displays influences from oriental architecture,[1][2] and it has been compared to both a minaret[1][2] and the tower of a medieval or fairy tale castle.
