Sueno's Stone

Sueno's Stone is just outside Forres, Scotland, and is the cornerstone of the largest and best preserved of the Pictish period. Tests show this monument dates roughly from 600 AD. The stone is carved with panels on all sides, each of which represents an independent history to the others. The interpretation of them isn't clear, however the most relevant studies suggest that they may be battle memorials (like the Romans have on columns, like Trajan in Rome). Other theories suggest that this stone was the central body of an impressive Celtic cross, but this is unlikely as there are no breakage marks.
