Ditched and walled enclosures in Prehistoric Iberia (4th-3rd millennia cal. BCE): Like oil and water
Published 2025-01-01“…We conclude that: (a) Chalcolithic Iberian enclosures are markedly dichotomous (ditched vs walled); (b) «mixed» sites are rare exceptions rather than the rule; (c) walled and ditched enclosures show important differences in key features (topographic setting, geographical distribution); (d) such differences cannot be solely attributed to geological factors. The paper will end with a discussion of possible explanations for this dichotomy.…”
