Sueno's Stone is a large Pictish standing stone located in Scotland, near the village of Ruthwell. It stands about 2.5 meters tall and is intricately carved with various symbols and figures, including a cross and depictions of animals. The stone is believed to date back to the 8th century and is one of the most significant examples of Pictish art. The stone is thought to commemorate a Christian figure, possibly a king or noble, and reflects the cultural blend of Pictish and Christian influences during that period. It is a key artifact for understanding the history and beliefs of early medieval Scotland.
