Pictish Stones are ancient stone monuments found primarily in Scotland, dating back to the early medieval period, around the 5th to 8th centuries. These stones are often decorated with intricate carvings, including symbols, animals, and human figures, which are believed to represent the Picts, a group of Celtic tribes. The purpose of the Pictish Stones remains a topic of debate among historians. Some suggest they served as markers for burial sites or territorial boundaries, while others believe they were used for religious or ceremonial purposes. The stones provide valuable insights into the culture and beliefs of the Picts during this time.
