Runestones are large stones that have been inscribed with runes, which are characters from ancient alphabets used by the Norse and Germanic peoples. These stones often commemorate important events, such as battles or the lives of notable individuals, and they can be found primarily in Scandinavia. The inscriptions on runestones provide valuable insights into the culture, language, and history of the time. Many runestones date back to the Viking Age, and they serve as important archaeological artifacts that help researchers understand the beliefs and practices of the Vikings and their ancestors.
