Walls not only for defense

The first wall of the fortification is formed by irregular stones of unequal size. It maintains up to 3.60 m in height by 1.60 m in width and has also two cut faces, one internal, conformed by small size masonry, and the other external, constituted by larger and better dimensioned pieces of stone. The fortification of the prehistoric settlements and villages located on high ground, takes place from the Bronze Age (1800-800 BC), at which time they were constructed with perishable materials. During the Iron Age (800 BC), many of these settlements, in the case of Troña, were still occupied and new ones started to appear, which is why they decided to renew and strengthen their defences using stone walls. Building a wall was a colossal job; you had to dig large pits and build parapets of earth and stones; finally, erect walls and crown them with wooden outer walls or stakes. The objective was to provide the village with protection in case of attack, but also with a symbolic element that increased its prestige. The control of the population that lived in the fort could be another of the functions of the wall. 
The first wall of Troña, that included the highest enclosure of the fortification, had a perimeter of about 360 m. A wall of the second enclosure, as a consequence of population growth, is about 327 m long and was developed on the north-western slope.

Indigenous pottery

The fragments of pottery found at the fortification, come mainly from the transit areas, that is, from the "streets" of the village, the place where the broken ceramic remains were deposited that were no longer useful for their inhabitants.
The containers used by the Gallacei are of different types and sizes (storage of fruits and seeds, liquids, flours ...). The jugs and containers of small and medium size -made up of globular recipients- were decorated with geometric motifs that were basically engraved with two main techniques: incision and stamping.
