The stone is called 'Sueno's Stone', set just off the main road near Forres. It is apparently a Pictish memorial - (a very big one!) to a leader who won a battle there. There is a fort over the other side of the road but we didn't see it. The stone is carved to show rows of decapitated enemies on the front side, and celtic cross and swirls on the reverse. It must be about 30' high.
