Ingvar runestones
The Ingvar runestones (Swedish: Ingvarstenarna) is the name of around 26 Varangian Runestones that were raised in commemoration of those who died in the Swedish Viking expedition to the Caspian Sea of Ingvar the Far-Travelled. The Ingvar expedition was the single Swedish event that is mentioned on most runestones, and in number, they are only surpassed by the approximately 30 Greece Runestones and the approximately 30 England Runestones.
