At the top of the mount of Nossa Senhora da Assunção stands a castro (hillfort) with the same name that offers unbelievable views over the whole valley of Minho. It was initially built at the end of the Bronze Age (8th century BC) but, due to its strategic importance, it was continuously occupied until the 1st century AD, as evidenced by its three lines of walls. In addition to the ramparts, several circular plan constructions and two sets of rock art are visible, one next to the chapel that exists there and the second at the highest part of the set, where the acropolis of the castro would be. We are able to discern cup marks, concentric circles, rectangular and serpentine cavities and even a footprint, probably dating back to the 3rd or 4th century BC, prior to the castro. After going through all the corners of this castle, don’t forget to contemplate the privileged view once more, before leaving.
