Rune stone with a mysterious dragon head in Söderköping church, Östergötland

The Rune Stone Fv 1966;102 is a 1000-year-old stone located outside Söderköping's St. Laurentii church, Östergötland. Gunnvat originally raised the stone, as referred to in the source material, but it was later found in the northern church wall in 1965 and now stands resting between the church and bell tower. The dragon head on the stone can be used to date it to between 1010 and 1050. The stone was raised in memory of Gunnvat's two sons, Torsten and Torlak.
