Arkils tingstad ("Assembly location of Arkil") 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. Another view sees the assemblies as meetings for the chieftains only who merely stated what they had decided to do and where they interrogated and punished their subordinates.Before the Christianization of Scandinavia, the pagan blóts were performed by chieftains and magnates. When Christianity arrived, the Christian rites and especially baptism were central to the community. It is possible that the Skålhamra clan created the assembly location in order to have settlements around the lake baptized by priests from Sigtuna. The inscriptions suggest that the location had no continuity from Norse paganism.Based on the styles of the inscriptions, the assembly location was created in the 1010s, and the runestones are some decades older than the Jarlabanke runestone U 212 which tells of the creation of another assembly location.

At Broby bro in Uppland, Sweden there are six runestones. U 139, U 140 and U 151 still stand by the road, but U 135, U 136 and U 137 have been moved a distance away from the road. The last three stones are in the style Pr2 and thus dated to the period 1020–1050, but the internal relationship between them shows that U 137 is the oldest one. They belong to a group of c. 20 runestones called the Jarlabanke Runestones that are connected to the local strongman Jarlabanke and his clan. Together with the Hargs bro runic inscriptions and the Uppland Rune Inscriptions 101, 143 and 147 these particular runestones, however, centre on the matriarch of the clan called Estrid. U 137 tells that Estrid and Östen have a son named Gag who dies, and when it was raised Östen was still alive. The other stones (U 135 and U 136) constitute a twin monument telling that Östen has gone to Jerusalem and died in the Byzantine Empire. Estrid and Östen had three sons: Ingefast, Östen and Sven, who built a bridge and a barrow after their father. These twin stones show that Gag died as relatively young as he is not mentioned on them. Estrid is the same person as the Estrid who is mentioned on a number of runestones in Täby and other locations (Hargs bro runic inscriptions and Uppland Rune Inscriptions 101, 143 and 147). This Estrid was the maternal ancestor of a great clan called the Jarlabanke clan, and she was the maternal grandmother of the powerful Jarlabanke who claimed to own all of Täby. The carver of the Snottsta runestone called U 329, where an Estrid and her brother Ragnfast are mentioned, was Fot who also made the runestones for the Jarlabanke clan. This strongly suggests that Estrid was born in Snottsta (also spelled Snåttsta), married Östen of Täby and married for the second time in Harg near Snottsta.
