Torghatten
Torghatten is a granite mountain on Torget island in Brønnøy municipality in Nordland county, Norway. It is known for its characteristic hole, or natural tunnel, through its center. It is possible to walk up to the tunnel on a well-prepared path, and through it on a natural path.
On 6 May 1988, Widerøe Flight 710 from Namsos to Brønnøysund crashed into the side of the mountain, and all the 36 passengers and crew died.
