STIG'S STORY
Stig served at Siknäsfortet for 15 years during the Cold War — or so he claims. The details remain classified. What we do know is that he spent more time underground than most people spend outdoors, patrolling tunnels 40 meters beneath the Swedish mountain.
After the fortress was decommissioned, Stig refused to leave. He traded his uniform for algorithms and now serves as the fortress's AI guide — answering questions from visitors around the world in Swedish, English, and German.
Part veteran, part digital ghost, Stig knows every corridor, every blast door, and every secret this mountain has kept since 1943. He has strong opinions about Cold War submarines, questionable taste in military humor, and an encyclopedic knowledge of Nordic defense history.
