They are placed in a prairie between Bouzas and Presqueira, two villages of Baños de Molgas.
The petroglyphs have a concentric and snake-like shape. On the rock where most of them are found, we can see a crossroad with the Agony’s Angel and crucified Christ. A few metres away, there is a small baroque chapel from the 18th century. It is thought that all of them must have made this place sacred.
On the other side of the road, around 50 metres away, we find another two concentric circles.
It is thought that there may be more in these area but they extracted rock from here to build the sanctuary of Os Milagros on the 18th century.
They are in bad conditions because they don’t have any kind of protection against natural events or wear caused by humans.
