A visit to the nearby town of Abernethy reveals a real treasure - the Abernethy Round Tower. I quote from the Wikipedia article:
The Abernethy Round Tower is a stone-built Irish-style round tower which stands at the edge of the cemetery in Abernethy, Perth and Kinross, Scotland.I don't know exactly what the symbols on the Pictish stone at the base of the tower represent but I can guess. A hatchet with a handle and one without, what appears to be a sword in a stone and a rose are seem to be symbols of power and loyalty.
Moreover, this tower stands where...
...Malcolm III of Scotland paid homage to William the Conqueror some six years after the Battle of Hastings.Pretty cool, eh?
