Borgarvirki is situated between Vesturhóp and Víðidalur in the north of Iceland. It is a volcanic plug that rises 177 m above sea level, dominating the surrounding landscape. Borgarvirki is a natural phenomenon, made out of basalt strata, although modified by men to better act as a military fortress as suggested by the Icelandic Sagas. From Borgarvirki there is a wide panoramic view over a large part of the region and a viewpoint telescope is there to help you locate some of the important landmarks.
