Here is a small enclosure detected in the highest platform of Senhora da Alegria set of enclosures.
In terms of stratrigraphy, it is posterior to the Early Neolithic occupation and it seems to be prior to the Late Neolithic one. It is a very small ditched enclosure, apparently oval, with only one gate. The ditch is deeper in the gate sides and progressively becomes lesser deep towards the back. It was filled with layers of stones and clay, with very few materials, mainly polished stone tools.
Inside, and not centred, there was only a fireplace, conserving large fragments of wood charcoal.
The plant and the inside fireplace remember other European small enclosures, namely in Ireland and in Italy. In Portugal, and from Late 3rd millennium, we have other examples in Alentejo, where a pit grave substitute the inside fireplace.
In fact, we are just start to become aware of the large diversity and complexity of the processes of enclosing that took place in Western Iberia Prehistory. New empirical data is emerging every day. But most of it still way from debate and scientific forums.
