Castro de Santiago walled enclosure was the first site I excavated in Fornos de Algodres, from 1988 to 1996 and in 2006. As Fraga da Pena, the site is displayed in the local archaeological museum. Here are the posters that can be seen there.
I call your attention to the last one. To a specific situation, where Santiago is an interesting case: the presence of all “chaine operatoire” for the production, use and reuse of polished stone tools.
