According to local folklore, the rocks surrounding Eigerøy Lighthouse have grooves carved by the wheels of the carriage belonging to Thor, the God of Thunder. The modern explanation is that the fascinating lines in the rocks are a geological phenomenon formed when hot magma filled cracks in older rocks. This produces so-called dykes of a coarse grained rock called norite cutting through anorthosite. Come and find out more about the stories behind the Eigerøy Lighthouse area!
Eigerøy Lighthouse (Duration: 1-3 hours)
The trip to Eigerøy lighthouse is a mixture of geology, history and beautiful marine landscapes. The majestic Eigerøy lighthouse was built in 1854 and is the oldest cast iron lighthouse in Norway. It is 32.9 meters high and has one of the strongest lights in Europe. The lighthouse was automated in 1989. The area is beautiful in daylight and is a perfect place to enjoy sunsets. Enjoy the magnificent scenery in the evening and see the rays of light from the lighthouse.
The walk to Eigerøy lighthouse is suitable for everyone, since it is mostly along a maintained dirt road. Along the path you can see the pale pink-grey weathering colour of the anorthosite which is dark grey on fresh surfaces. On the walk to Eigerøy lighthouse you are surrounded by Magma Geoparks unique geology, as you are entirely within the large crystallized magma chamber known as the Egersund-Ogna anorthosite. The anorthosite has been cut by several long, narrow, coarse-grained dykes. The dykes consist of a rock type called norite – named after Norway. You will also see another geological speciality – a “breccia” where blocks of anorthosite are enclosed in norite.
How to get there: Follow road 502 from Egersund to Eigerøy. Then follow the signs leading to Eigerøy lighthouse.
