For those interested in history and the Icelandic Sagas, Borgarvirki is a very relevant place to visit. Although originally formed naturally by an ancient volcanic plug of columnar basalt, that base is believed to have been transformed into a defensive fortification dating around the Settlement (879 - 1030 AD). There are some debates about whether that is true or if it was simply used for peaceful purposes but either way it is a great spot to see and perhaps decide for yourself. Borgarvirki was one of the first historical sites in Iceland to be granted conservation status in 1817 and was last renovated in 1949. It is the perfect pit stop when driving in the north of Iceland, situated between Vesturhóp and Víðidalur.
