The Holy Spirit Grotto (La Gruta del Espíritu Santo in Spanish), in Corinto, Morazán, El Salvador, is a registered national monument of petroglyphs. The archaeologist Wolfgang Haberland performed studies in the late 1970s indicating the art belongs to the pre-Classic stage of Mesoamerican civilization.[1]
