Sallent route: Resistance core (NR) 109-110.
There are numerous bunkers on this route but some are in very poor condition or difficult to access. In addition, some of these sites cannot be seen as they are in private fields.
Several of them have been adapted so that they can be visited.
In Sallent, in "Del Paco" neighbourhood, there are two on the way to the San Mamés viewpoint, located on a small hill of the same name. Climbing up the path on the right is a bunker for a machine gun. A table for a machine gun was built inside it. From here a small path leads off and a few metres away is a small field where a double machine-gun emplacement is located. We can see its loopholes located in the same counter-terrain wall. The purpose of both works would have been to beat the terrain around Sallent in a semicircle whose diameter is approximately the line formed by the Aguas Limpias river, prolonged by the Gállego.
