Runestones are large stones that have inscriptions in the ancient script known as Runes. These stones were primarily created during the Viking Age, around the 9th to 11th centuries, and are often found in Scandinavia. They served various purposes, including commemorating the dead, marking territory, or celebrating significant events. The inscriptions on runestones can include names, dates, and messages, providing valuable insights into the culture and language of the time. Many runestones are decorated with intricate carvings and symbols, reflecting the artistry of the Norse people. Today, they are important archaeological artifacts that help historians understand Viking history and society.
