The sandstone outcrop
Hellnaskagi is on the property of the southernmost farm of the country,
Gardar. It stretches westwards into the Dyrholar Lagoon and on its
top are the ruins of farm Hellar, which was abandoned in 1909.
Other manmade caves, Graenkelluhellir, Hrossatrod and Heyhellir (now
collapsed), are there as well. Cave Badstofuhellir
is best known for Reverend Jon Steingrimsson's stay there for a part
of the winter of 1755. At that time, the cave probably
was connected to the farm houses as a tunnel on the right
hand side of its entrance suggests. Jon chiselled a
larger space for himself, and lived in the cave with his
brother for a while. During the stay, Jon studied the
German language and got interested in the history of
volcanism. When the brothers were preparing their stay
in the cave, a major eruption started in the Katla Area.
District Magistrate Jon Sigurdsson wrote a report on it.
based his personal and much more detailed report on it.
Later in his life, after having served as a Reverend in the
Sida Area for years, he wrote a renowned report about the
Skafta Eruption (Sida Fires; 1783-84), which is a priceless
source for scientists.
is about 6 metres long, almost 3 metres wide, and 2 metres high.
The arch shaped nieche in the end wall probably is the work of Jon
Steingrimsson. The walling in the entrance its woodwork with doors
and windows made the cave a comfortabel abode. The last time the
cave was used, some sheep were kept there.
