“Guardias” is a project based on family files, which runs through several generations using their profession as a shared link. Family relationships create a unique and very personal system, contradictory and ever-changing, in which certain roles coexist generating rules or patterns, usually created unconsciously, that are assumed by the new generations through a thread of harmony. In almost all family systems there are so-called "family myths", systematized, shared beliefs that are channeled through interaction. They are often expressed by secret rules, which only members know and normalise. These myths determine intra-family relationships and possess a homeostatic character, as they self-regulate, stabilize and essentially, reject change.
