On one of the paths connecting the chapel of San Benito de Cova do Lobo with the penedo do Tangaraño, there is a small rock engraved with a cross. This cross, formed by two grooves about 16 cm long, crossed at right angles, with a width of about 2.5 cm and a depth of 2 cm, does not seem to mark any boundary between current municipalities or parishes. Its meaning could be related to ancient pagan rites around the rock or to the delimitation of some old territory, making it an interesting vestige of the area's past.
On a small path that runs from the chapel of San Benito de Cova do Lobo to a large rock called penedo do Tangaraño, there is a small stone with an engraved cross. This cross is made with two deep lines, as if someone had drawn them long ago. It does not mark the border of any current town, but perhaps, years ago, people used it in ancient festivals or rituals, or to mark a special place. It is a mysterious sign that helps us imagine how people lived and thought in the past.
Along the route connecting the chapel of San Benito de Cova do Lobo with the penedo do Tangaraño, a small rock with an incised cross can be found, composed of two grooves approximately 16 cm in length, crossed at 90°, with a width of 2.5 cm and a depth of 2 cm. The absence of a current boundary function rules out its use as a territorial marker, suggesting interpretations linked to ritual practices of pagan origin or the symbolic delimitation of ancient coutos. This type of engraving, common in Galician-Roman and medieval contexts, may be associated both with processes of Christianization of preexisting sacred places and with marks of protection or consecration of spaces of worship and transit.
