It is currently a residential building, fully integrated into the town’s activity. It contains three business premises, two apartments and a loft/studio. In this paper, we schematically present the findings from the historic building analysis of this tower house as an example of the continuous adaptation of a building to the requirements arising from social developments, from the Late Middle Ages to the present day.analisi historiko konstruktiboaPortalondo dorretxeaHistoric building analysisPortalondo tower houseArkitekturaEuskal HerriaHistoriaintroduction
