The detailed investigation of dwelling no. 14 (Precucuteni II phase) from the Isaiia site brings interesting and, in some instances, novel data concerning the building system and the internal architecture of the Early Chalcolithic housing. Also, the artefacts from inside the dwelling and from the surrounding features bear witness about prehistoric crafts like pottery manufacture, stone knapping and polishing, animal hard tissue working, about the relations with neighbouring cultural areas, and, last but not least, about the ritual behaviour of the Precucuteni communities.
