The Lapa de Gargantáns is a Neolithic menhir located in the parish of Gargantáns, in the Spanish municipality of Moraña, in the province of Pontevedra. It was discovered in 1958 and due to its characteristics, unique in Galicia, it was adopted as the predominant icon of the coat of arms of Moraña. It is 1.92 metres high and 50 centimetres in diameter. It is conical in shape and its square base has been cut off, so it is likely that its original height was greater. Twenty cups are engraved on its surface. In archaeology, a \’cup\’ is a small artificial hole carved into the surface of some rocks, together with several angle-shaped marks and two twisted lines. The word \’patella\’ in Galician, among other meanings, designates a stone that indicates a burial, but its exact function is unknown, and some archaeologists associate it with funerary, religious or commemorative signs, or ancient territorial boundaries between tribes.
