Man stopped being nomadic and settled on Plomo Hill. More than 5,000 years have gone by since they established themselves on this flat-topped hill, which gave them security, proximity to a fertile meadow and the seashore, which offered them so much sustenance.

Plomo Hill was home and refuge for a maximum population of almost 100 people, who inhabited it between the end of the fourth millennium and the beginning of the third millennium before Christ, the occupation possibly lasting until the middle of the third millennium. It was therefore one of the main settlements of the end of the Neolithic-Chalcolitic in the peninsular.

A fortified settlement with a 130-metre long wall and circular huts, while in the area immediately below one can see the remains of a cemetery. The inhabited part of the site is 3,200 square metres, surrounded by the wall which was located in the most vulnerable parts of the settlement; that is, to the west and south.

The village houses had stone bases. From the materials found it has been deduced that its inhabitants were already adept at the art of hunting, in the cultivation of cereals, in shell fishing and in domestic livestock. There is also evidence of two kinds of textile plants, flax and esparto grass. At the same time, social inequalities between the houses have not been found.

At the bottom of the hill the necropolis was found, although all that remains is a small funeral monument, called “tholos”. A circular-shaped construction, marked by four large stones in its interior. It would possibly have been closed on its upper part by a “false dome”: a system whereby each row of stones projected out from the previous, increasingly narrowing in height.

The monument served for the collective burials of the inhabitants following cremation.
