I think La Grande Roccia holds a great power.
While you're walking in the half-shade of a beech-wood suddenly it'll appear in front of you
as a shining silver dome, as an UFO...
And when you'll approach it, you'll find out that it's cut in two by a deep break as chopped by a big force. Beside it there's a nice spring. And it's covered by engravings.
So this was a sacred place for ancient Ligurians.
This site it's very suggestive and I believe "that" strong energy is still there.
