Borgarvirki is a
prominent landmark on the way through the Huna District. This natural
fortress, somewhat fortified by the people in the area in the past, is
situated on top of a 177 m high hill between Lake Vesturhop and the
Vididalur Valley. The fortress has 10-15 m high natural ramparts with
a 5-6 m deep depression in the middle. The man made part with the main
entrance was reconstructed in 1949-1950.
Two ruins of
human habitation and a fresh water
well are inside the fortress. No one knows for certain who added to
the fortifications, when or why. It has
been suggested that the people of the Huna District, who
were under constant threat of attacks by the chieftains of
Borgarfiord, used it for defence in the 13th
is supposed to have been under siege and both times the
armies from Borgarfiord had to leave without results.
