La Hoya, Alava

• Middle-Late Bronze Age: in this early period, the fortifications, as well the houses, were all made of wood.
• Early-Middle Iron Age: construction became more complex using mixed formulas with stone, wood and adobe. Most houses were near the wall in this period.
• Late Iron Age, with a cultural context that some classify as Celtiberian, shows important changes in urbanization: with paved streets and plazas that form a reticular structure. The wall is also rebuilt on stone. This final period also shows great advancement in the technologies: potter's wheel, elaborated blacksmithing, etc.
