The Menhir of Meada is believed to be the largest megalithic monument in the Iberian Peninsula entirely carved by humans[1]. Standing in the Serra de São Mamede Natural Park in Portugal's Portalegre District, this massive monolith of coarse-grained porphyroid granite is situated 12 km north of Castelo de Vide[1].
