Twenty-four years after the shrine had been left behind at Steinvikholm, the Nordic Seven-Year War led to Swedish occupation of the area in the spring of 1564. Swedish soldiers now moved the wooden coffin from the castle to Fløan Chapel on the mainland near by. Already on 8 June that same year, after Swedish forces had been driven back, the coffin with St. Olav’s body was brought "in great procession" from Fløan to Nidaros Cathedral, and lowered into a brick grave inside the church. It is now uncertain where this grave is.
