1970: The investigation of the archaeological site begins, after the announcement of Mr. Esteban Gonzalo Argüello, neighbour of Quintanilla de la Cueza, who knowing the existence of fragments of tiles and other remains in the land called La Tejada, brought to Diputación de Palencia a fragment of mosaic that had found in the place. The President of the institution that year (and at the same time director of the Archaeological Museum of Palencia), Mr. Guillermo Herrero Martínez de Azcoitia, ordered the excavation to Mr. Miguel Ángel García Guinea, Director of the Museum of Prehistory and Archaeology of Cantabria, who had concluded the excavations in Cildá.
