Hemsö Fortress

In the middle of the Ångermanälven estuary, just outside Härnösand, is the island of Hemsön, and here you will find Hemsö Fortress, which is historically one of Sweden's most significant defense facilities. The fortress has a past as the Coast Guard's largest facility and is the only one of its kind preserved; from the main facility (HÖ1) which is blasted into the 140 meter high Storåberget, a mile-wide view of the coast, sea and islands is given.

From a historical perspective, the area has repeatedly been exposed to intrusion by what is considered the enemy. Due to this, the area has had a great strategic significance for the Swedish defense, which in 1953, after a defense decision on increased resources for the defense, began the construction of Hemsö Fortress. Four years later, the top-secret mountain facility was completed.
