The Ribas escarpment, near the fortification with the same name, is an example of a type of military construction whose objective was to militarily reinforce the natural barrier of the hilly terrain.

From the top of Serra de Ribas, you can still see the manmade slopes. Some sections of this retain the original stonework, which made the incline even steeper so as to impede the invaders’ ascent. This military construction extended between the redoubts of Ribas and Mosqueiro.
