It is an elongated plateau in a northeast-southwest direction that presents steep slopes in all directions. It has dimensions of 500 meters on its longest axis, about 270 meters on the narrowest side and an area of ??about 10 hectares.

Archaeologists especially highlight its landscape values ??with a native vegetation of holm oaks and other species typical of the Mediterranean scrubland.

The site has been the subject of some limited archaeological interventions and the general lines of a Master Plan were even started to be drawn up to address its comprehensive treatment from research and protection to dissemination and enhancement, although progress was only made in that sense .

The execution in Cabeza Baja of an emergency excavation in 1986, motivated by the increase and extension of archaeological plunder, offered a series of key archaeological data to define the entity of the site. The data obtained in the excavation indicate that the Cabeza Baja de Encina Hermosa oppidum was founded between the end of the 3rd century BC. and the middle of the second century and developed a settlement that should broadly follow the typical Iberian urbanism of the Alto Guadalquivir.

The first continuous occupation of Cabeza Baja (early 2nd century and late 3rd century BC) was probably by contingents of Túrdulo origin arriving from Obulco, although other nuclei such as Iponoba, Tucci or even the Iberian nuclei of Alcalá must not be ruled out. the real. The excavations indicated the existence of diverse structures; the existence of an Iberian wall around the plateau was demonstrated. The thickness of the wall can be estimated at 3 meters.

The finding of a fire level was indicated as a possible cause of the abandonment of these dependencies.
