These are the famous lands settled in mediaeval times by the Order of Saint James of the Sword, vital in the conquest and Christianisation of the territory that would later become the Kingdom of Portugal. It is from this memory that the name Santiago derives; and associated with this name is Kassém, from the Arabic, the civilisation that inherited the important Roman metropole of Miróbriga and various Celtic and prehistoric vestiges. Over time, the rural space was divided up and an attractive mosaic of working farms gave way to estates and oak groves that define a landscape of greenery and life.
