About
About Castro of Zambujal
Key Atlantic Chalcolithic fortified settlement on hill spur above Sizandro valley near Torres Vedras, 50 km north of Lisbon. Intensively excavated 1964–73 by E. Sangmeister & H. Schubart revealing 5-phase Copper Age proto-town (c.3000–1700 BCE) with stone circuit walls, bastions, barbican gateway, tower-houses and foundry. Represents Bell Beaker type-site alongside Vila Nova de São Pedro. Thermoluminescence and radiocarbon chronology anchors Iberian Chalcolithic sequence. Strategic control of Torres Vedras fertile plain and copper route from Alentejo. Fortifications show architectonic sophistication paralleling Los Millares. Managed by Torres Vedras Museum.
