Slab of Gargantáns Monument · Moraña, Caldas, Pontevedra A menhir 235 centimetres in total height, of which 192 are visible, discovered in 1958 by the schoolteacher Carlos Paratcha, the first to be attributed without dispute to Galician prehistoric megalithism; it is dated between the fourth and the middle of the third millennium BC. Conical in shape with a square base, now cut, it retains about twenty engraved cup-marks along with angular marks and two winding lines, whose purpose is unknown: it has been linked to funerary or religious signs, or to ancient boundaries between tribes, and it served as a boundary marker between the parishes of Gargantáns and Santa Xusta de Moraña. It is the main element of the municipality's coat of arms, and nearby, next to the Romanesque church of San Martiño de Gargantáns, stand the much-faded remains of the castro de Paraños.
