A small town
The Tramontane of Carvalhelhos Castro is one of the most important of the Iberian Peninsula. Nearby you notice a system of parallel ditches (3 moats and as many lines of walls), access ramps and walkways. This defense system is only found in Portugal (in some forts of the Tras-Os-Montes) there is also a stretch of stones "settled down" (something like "rooted", nailed to the floor) in the area where people lived. It is a small town that survived on agriculture and livestock. Of the houses, which impressed me most, was a circular building near the river (starting to drop due to the slope). It was a small building with a small round outer wall (as a kind of tiny porch) that was used to guard livestock.
