(Monte Musinè, is sure one of the most famous place for misteries. Peter Kolosimo wrote about it and about some stones on it. It's known for UFO too! But anyway, it's sure that this place it's allways been a very special place since prehistoric times).
Along the way to the top of the mountain you can find a lot of standing stones, but most of them are surely natural. I found this "alignement" on a book about megalitism on italian and swiss alps called "spiriti di pietra" by Massimo Centini, and I decided to go and to find it.
