Pre-historic architectures reveal a profound knowledge of building materials and
their selection and application. Depending on each geographical context or functional needs,
pre-historic man developed and applied different building techniques.
Archaeological vestiges from several pre-historic settlements of southwest Iberia has shown that
stone, wood and earth were the main materials used on domestic structures. Earth mortars seem
to be the most frequently used, probably due to the abundance of clayish materials in most geographical
contexts and the facility on handling them.
Several earth building techniques were identified in settlements located in south of Portugal.
Some of them are being object of detailed studies, based on material traces obtained in habitat
places of Defesa de Cima 2 (Évora), Alto do Outeiro (Beja) and Alcalar (Faro).
The analysed materials are composed by samples of earth mortars from the covering/ filling of
vegetable structures, stacked earth walls, renderings and mudbricks.
