General characteristics
The Copper Age
Also known as the Chalcolithic or Eneolithic Period, the Copper Age was a time of diffuse and sporadic use of copper for a limited number of small tools and personal ornaments. If the age is defined simply as the time when copper first began to be used, then localized Copper Age cultures existed in southeastern Europe from the 5th millennium bce. On the other hand, if it is defined as the time when copper was an established element in the material culture, then it must be dated from about 3200 bce in the Carpathian Basin and southeastern Europe, slightly later in the Aegean, and later still in Iberia.
In these early copper-using societies, copper had no importance in subsistence production, and the tools made could hardly compete with those of flint and stone. The new material had prestige, however, and was used to adorn the deceased. It was at this early stage of metal use that one of its important roles was established: to mark and articulate social prestige and status. The Copper Age as a distinct stage developed only in a few regions; these included groups in areas as far apart as Bulgaria, Bohemia, the Aegean, and southeastern Spain.
One of these remarkable centres of early copper use was in southeastern Spain. Situated in the Almerian lowland, in an area confined by the coast and the mountains, it was a densely settled region with large nucleated and often fortified hilltop settlements of surprising architectural sophistication and with a rich and inventive material culture known as the Millaran Culture, after the site of Los Millares. Like contemporary sites in the region, Los Millares was located so as to overlook a river from a promontory in the foothills of higher mountains. The sides and plateau of the hill were fortified with massive stone walls, regularly placed semicircular bastions, and outlying towers. These created a well-defined and protected space of approximately 12 acres (5 hectares), with several occupation phases and of some complexity. The settlement was townlike, with rows of stone houses, alleys, and a central communal place within the walls. An artificial watercourse may have led to the settlement. There was specialization of production between households. Outside the settlement was a cemetery containing more than 100 megalithic tombs with corbeled chambers used as collective burial places.
