If you were to build a perfect fortification and place it in a strategically important place, you could probably not match the rock formation Borgarvirki. That is to say, if you were also in medieval times where weapons of choice were a sword and a shield. Located approximately 180 meters above the sea level with a magnificent view in every direction it has a perfect placement. Although it looks very much like a man-made fortification when you approach it, it is actually a natural formation.
More interesting as a natural wonder of basalt columns
Borgarvirki or The Rocky Hill Fortification as it could be translated into English is a rocky hill made of basalt columns. The rocky hill is 10 to 15 meters high with a hollow in the middle, surrounded by 6-meter walls and has an entrance to the east. It is not big and probably never housed a large group of armed men. Although much of the time from settlement to medieval times are quite well documented in Iceland in the Sagas, no battle is mentioned at Borgarvirki. So the taught that it was ever a fortification are only speculations. One of the reasons that stories about fortification have developed is the fact that at the entrance is a stonewall built hundreds of years ago. But as a natural wonder, Borgarvirki is interesting to visit and an interesting geological formation.
Easily accessible from the Ring Road in Iceland
Borgarvirki is located only 10 kilometers from the Ring Road or Road 1 in Iceland on a turn to the north on Road 716. It is also only a short walk from the parking lot up to the top of Borgarvirki. There you can both enjoy the magnificent view over Vatnsdalur to the south and Vatnsnes to the north. You also have a good opportunity to see the magnificent basalt column formation.
