Skarrsten A. Compasses carved in stone

"All along the southern Norwegian coast we can find compasses carved in rock. These compasses can also be found in Sweden, Finland and on the Faeroe Islands. There is only one know compass like this outside of these four countries, that is on the top of Mont Orgueil Castle on the east coast of Jersey. Research by Johan A. Wikander, the outmost expert on this type of rockcarving in Norway, has established that most of these compasses has been carved by pilots on high points, at their lookouts. These were to be used when they saw a ship signaling for pilot. If the weather turned bad or snow- or rainshower came in, he would still have the bearing for the ship. These compasses are around a foot wide (smallest 17 cm, biggest 68 cm) with different layouts and use of symbols for north an east". Изображения компасов, высеченные в камне на побережье Норвегии.
