The position of Les Devees is part of the protection network of the village of La Fatarella. The shelter that is still preserved was built by the soldiers of the position and used as a room to sleep and shelter.

Above the shelter you can see part of the trench line, with the remarkable zigzag line form that allows reducing the effect of the enemy projectiles and facilitates the defence. It was originally about 180 cm deep, although the effects of sedimentation have reduced its depth to the current size.
