“On Vatnsnes in Húnafjörður in North-Iceland is an awesome rock-formation called Hvítserkur. It is a 15 meters’ high monolith and stands alone just off-shore from the land. It looks like an animal of some sort, an elephant or a rhino – or even a dinosaurus drinking. It is just awesome! Especially as there is a lot of fulmar nesting in it so it seems to be alive and it is half-white from their excrement – I just love monoliths like this!
The tale goes that Hvítserkur is a petrified troll.”
Borgarvirki lies between Vesturhóp and Víðidalur in the north of Iceland, and at 177m above sea level it dominates the surrounding region. Made out of basalt strata, it has been used as a fortress for centuries.  Borgarvirki is a natural phenomenon, altered by humans in earlier centuries. In 1949, the main entrance was renovated by workers.
Upon the fortress is a viewing dial.
It is accessible to visitors travelling around the peninsula of Vatnsnes.
