Arkils tingstad is the remains of the Viking Age thing or assembly location of a hundred in Uppland, Sweden. It is situated on the outskirts of Stockholm. The remains consist of a rectangular stone formation and two runestones.
The runestones and the assembly location were created by the Skålhamra clan who also had the two Risbyle Runestones made across the lake near their estate. It consequently appears that they owned land on both sides of the lake. They also made the runestone U 100 at a path in the forest.
Scholars disagree on the function of a Viking Age assembly location. According to one view, all the people in the vicinity assembled there in order to reach agreements and to mete out justice.
