Castro of Zambujal

The Castro of Zambujal is a Chalcolithic age archeological site in the municipality of Torres Vedras in the western litoral area of the Centro Region [1]. The site was discovered and interpreted in 1932 by the Portuguese archaeologist Leonel Trindade, who made the first investigation in 1944 and, together with Aurélio Ricardo Belo, from 1959 to 1961 [1]. The site was first occupied in the Chalcolithic period, at the beginning of the 3rd millennium BC [1]. The site and surrounding land was specifically tied to a chalcolithic settlement that constructed a wall around itself to protect its community from attack [1]. The houses on-site were oval shaped, approximately 6 metres in diameter, and made from adobe [1].
