Hi Martin and Anne! It is actually a sculpture put there deliberately. It is part of the sculpturelandscape Nordland spread out over half of northern Norway. This particular sculpture is made by Anish Kapoor and is called "Eye in stone". Link to the project:http://www.skulpturlandskap.no/ . We have made it a thing to find and photograph all the sculptures during our visits to the north. We are not halfway there yet. Part of the fascination is that most of these sculptures are placed in very remote areas so you have to be dedicated to find them. At the same time it is also a great geography lesson! :-)
