The monolith, carved in gneiss, is a kind of column measuring 4.20 m in height for an estimated weight of 2500 kg; its circumference is between 1 m at the top and 2 m at the base1. It could be a funeral monument dating from the Bronze Age or the Iron Age, and not a true menhir.
The pseudo-menhir is found overthrown near the Dora baltée in 1988.
It is believed that the original location of the stone does not correspond to the place of discovery and the stone was undoubtedly used in 1921 in the construction of the reservoir of Mazzè.
Interesting are the similarities with the Piedmontese stelae of Chivasso
(4.0 m high) and Lugnacco (3.85 m high) and the presence of small bowls hit in stone. A similar stele is the stela of the Golasecca culture of Castelletto sopra Ticino, in which weapons are engraved. It can be dated between the 7th and early 6th century.
