The Craw Stane, a 'Class I Pictish Symbol Stone', located to the south of the village of Rhynie in Aberdeenshire. This stone has a salmon and Kelpie (water elephant/Pictish beast) carved on it, however these are difficult to make out in this photo due to lichen growth.
The Picts are known chiefly for their elaborately but regularly decorated memorial stones found in profusion throughout eastern Scotland from Shetland to the Firth of Forth. However, much more is actually known about them than that.
Pictish boat: St Orland's Stone - Hmmm... I wonder what the significance of the cut-out is....
