Siknäsfortet (Siknäs Fort)

Forty meters deep in Hömyrberg on the Siknäs Peninsula, you’ll find a top-secret underground fort, built to defend Töre harbor, Sweden’s northernmost deep-water port, and to delay a hostile advance towards Boden along Highway 13 (E4).

Guided tours are offered during the summer.
