This stele-menhir is 4.70 metres high and has a maximum thickness of 0.5 metres, with a flat face. It has engravings on both faces and one of the lateral areas. The techniques used are perforation forming grooves, bas-relief and fine incision. One face shows representations of several axes, a double zigzag line, a crosier, a serpent, a line that defines a kind of waist, several indentations and circular and sub-rectangular motifs, sometimes with internal indentations. The other face shows another crosier and more indentations. Its location in front of Perdigões, about 3 kilometres to the east, could be meaningful, as this ceremonial enclosure aligns at 90º, i.e. with the equinoxes, together with the large stele-menhir of Herdade do Barrocal and the Monsaraz elevation on the horizon).

The presence of crosiers. Objects that integrate many votive funerary sets of Alentejo megalithism, crosiers are an equally common element in megalithic art, particularly on menhirs. Interpreted as symbols of distinction and power, they relate to certain prominent positions within Neolithic societies. In Reguengos de Monsaraz, these representations are visible on several menhirs: Bulhoa, Barrocal, Herdade das Vidigueiras or menhir 37 of the Xerez cromlech.
