Route of the bunkers in Sallent de Gállego, Lanuza and Formigal

All of them belong to the "P LINE"

The Tena Valley, due to its proximity to the neighbouring country, France, has had the mission of protecting the rest of the country from possible invasions. That is why throughout its villages you can see different fortifications, such as castles from the 15th-16th centuries, forts and recent 20th century bunkers.

The most recent fortifications are those belonging to the P Line or Line of the Pyrenees. Commissioned by General Franco after the end of the Spanish Civil War, it is the largest defensive structure built in Europe after the Second World War (autumn 1944), as it covers the entire Pyrenees mountain range, from the Bay of Biscay to the Mediterranean. It is also Spain's largest military engineering work, the purpose of which was to seal the border with France to protect against a possible invasion through the Pyrenees. This work was never completed and never entered into service.

In Aragon, line P is divided into 5 sectors and each one into resistance nuclei (N.R.), in the area of Sallent de Gállego there are N.R. 108, 109 and 110.

SAN MAMÉS

SAN MAMÉS

Line P. Route of the bunkers. San Mamés. Sallent de Gállego.

They are part of the Resistance Nucleus 109, called “Sallent”.

We leave from the Town Hall and to the right we cross the Roman bridge (El Paco) until we reach the El Paco neighbourhood. Once there, follow the signs to San Mamés. Before reaching the viewpoint, we will find the first bunker. If we continue to the right along a small dirt track, we will find the second bunker. To return, go down the slope and you will reach the square.

0.91 kilometres - Easy.

LANUZA

Line P. Route of the bunkers. Castiecho de Lanuza.

They are part of Resistance Nucleus 108.

On this route we find four bunkers, although if we combine it with the following route we will be able to see five bunkers in the same route.

We start on the track on the road to Lanuza that leads to Panticosa and a few metres further on we find a signpost on the right indicating the way to follow. It is a short but intense climb. Almost at the top there is a diversion to the right that takes us to the first bunker. We retrace our steps and continue climbing a few more metres until we reach the clearing at the top and there we will find the second bunker, with a panoramic view of the Lanuza reservoir and the Búbal reservoir.

We go down the way we came up and rejoin the track. Continue a few metres and you will find another signpost on the right. As soon as you take the path, you will see the first bunker on the left, which is very large and where you can see some inscriptions engraved on a table. We follow the path that takes us a few metres further on to a bunker, one of the largest that is clean and characterised by its triple arch. We retrace our steps and return to the track to return to the starting point.

3.22 kilometres - Easy.

Line P. Route of the bunkers. Lanuza.

As soon as you take the track that leads to Panticosa, a few metres after starting out, you will find a path on the left that will take you to the bunker in 5 minutes. The characteristic feature of this bunker is that inside we find the result of the passage of time and humidity: stalactites and stalagmites. This can be combined with the Castiecho bunker route.

0.34 kilometres - Easy.

Line P. Formigal.

They are part of Resistance Nucleus 110, the most advanced of all.

To enjoy the Formigal bunkers, you have to go by car to the Sextas car park.

Once parked at the top (closest to the curve of the saddle), there is a sign indicating the way to the GR11. Follow the signs towards La Frontera and a few metres further on you will find the first one. There are three in a row, of which only two have been enabled.
