The tumulus stands on a height close to the stream of La Mediana or Ciervos, which made it a landmark visible from a distance.

The tumulus stands on a height close to the stream of La Mediana or Ciervos, which made it a landmark visible from a distance. It consists of a central chamber, probably circular, made of slate slabs set vertically, where offerings and burials took place. Over and around the chamber lies a tumulus of stones and earth, which gave the monument its size and distinction.

In the post-medieval period the tumulus was plundered by treasure hunters, who disturbed the chamber and removed the offerings and grave goods deposited in it. The dating given above is based on the objects that remain.

As with many others, its function was not only funerary: it also served as a marker related to the ownership of land, its use, and the control of livestock routes (vías pecuarias). It is possible that the tumulus marked the division between the pastures of the prehistoric populations who visited Campo Azálvaro seasonally with their livestock.

The tumulus is reached from Mediana de Voltoya by taking the local road towards Urraca Miguel, to the south-east. It is signposted and described on site, and protected by a metal fence that keeps out livestock and other large mammals. Its maintenance and study are managed by the Junta de Castilla y León.

Burial mounds of this kind in the northern highlands of the Iberian Peninsula are usually placed in spots of great visibility, often on ridges, and are built of local materials.
Tradition and region
About this kind of monument
Iberian tumuli
Most of the Atlas's Iberian mounds lie in the northern highlands, especially the Basque country, where prehistoric collective graves are found in great numbers. Archaeologists there separate dolmens, which have a stone chamber covered by a mound of stones and earth, from "tumuli" or mounds that have no chamber but were used in the same way, for collective burial. Roughly 800 dolmens and about 500 mounds are known in the Basque Country, though some of the mounds may be dolmens waiting to be excavated.
Both kinds are placed in spots of great visibility, often on mountain ridges, and are built of local materials; the larger ones tend to be in lowland areas and the smaller ones in mountain zones. The dead were placed in the chamber or under the mound over generations, and older remains were moved aside to make room for newer ones, which is why very few Basque monuments have a clear layered record. Megalithic burial arrived in the late Neolithic, was in constant use in the Chalcolithic and Early Bronze Age, and in some mounds continued as late as the Iron Age.
Across Iberia the picture changes with the Bell Beaker phenomenon of the late Chalcolithic, which brought individual graves, often under mounds, in contrast with the collective graves that came before.
Dating is difficult, because few mounds have been excavated and the collective burials were disturbed, so the Atlas gives broad typological ranges.
When visiting, look for low circular mounds of stone on high ground in pasture, often with a ring of larger stones or a dip in the centre where a chamber may have collapsed, and for neighbouring stone circles on the same ridge.
