Thristapar and the last execution in Iceland 1830. 

Practically on the Ring Road in the northwestern region of Iceland is an interesting place called Þrístapar or Triple Hillocks. Although this part of the area is well known for its cone-like hillocks called Vatnsdalshólar (Water-valley-hillocks), most of the small hillocks are on the south side of the road. Hundreds (or some say thousands) of them are in a cluster called Vatnsdalshólar scattered over a five-square-kilometer area.

Þrístapar, on the other hand, which consists of three adjoining small hillocks, is on the north side of the road. Around them are only two or three other smaller ones.

On a cold day at the beginning of January in 1830, a double beheading took place at Þrístapar, when Agnes Magnúsdóttir and Friðrik Sigurðsson were executed. They had been sentenced to death for murdering Natan Ketilsson and Pétur Jónsson at the farm Illugastaðir, located on the west side of the Vatnsnes Peninsula. The slaying took place two years before in March 1828 and was quite brutal as both men were knocked through the skull with a hammer, stabbed multiple times, and burned when the farm was put to flames after the atrocity. As the district commissioner at the time of execution was of the opinion that vandalism was far too frequent in his jurisdiction, he decided to make the execution an example and a warning. After the beheading, the two heads were put on a stick-on top of Þrístapar for display, and the corpse buried in the field nearby.

This was the last execution in Iceland.
