Going up the Monte de Nossa Senhora da Graça, you'll find the homonymous hill fort, an interesting witness of the "castro" culture and settlements. To get there, you'll have to pass through the locality of Valinha, in the Ceivães parish. On your way to the chapel, notice the many hill fort remains.
You’ll get to a conic granitic elevation located at 1000 feet high where it's possible to observe some traces of this type of settlements. If you look carefully, you’ll be able to see some round structures and the remains of the typical wall construction system, which are likely to have been occupied since the Late Bronze Age till Romanization, between the 5th century BC and the 3rd century AD.
You’ll get a magnificent view of this hill fort from the one of Castro de Nossa Senhora D'Assunção. Moreover, both hill forts dominated the middle course of Minho River, from which they would obtain subsistence. Can you imagine how lucky these peoples were, being able to constantly enjoy these amazing views?
Among the archaeological assets found there, it stands out a variety native ceramics, pieces of tegula, lithic materials and bronze artefacts.
However, the main attraction is the sublime panoramic view available, especially the one over Mouro Valley.
