In hills such as 480, 500, 510, 496, 477, 371, 377, 378, 356, 426 (in the Vilaverd Valley), 402 .... and others, we find hundreds of kilometers of trenches with elements of this type of fortifications: shooters, shelters, command post . Infrastructures that have been buried over the years.

Elevations such as the 287 that was defended by the 50th Battalion of the XIII Brigade of the 35th Division, known as the Mickiewicz Battalion, which integrated the Polish brigades. Or the Cucut area where the international brigades such as the Marseillaise and Garibaldi fought. Historic fortifications such as the "Punta del Cucut" (defended by the 45th International Division), the "Pila", "Malees", Anís hill or the Coso (hills 350 and 341), the hill 705 ( where in the direction of Gandesa and at the roundabout towards Tortosa and three kilometers turn right (Signage Fontcalda). Follow the road and turn left for the dirt road (sign hill 705) and climb to the top of the hill ), cannot be forgotten.

These hills are not just geographical slopes, they are part of history. Each hill, each elevation, is a fortress built by Republican troops to prevent the advance of Franco’s troops. Places that in battle and with the passage of days, become immense mass graves. Survivors take refuge in miles of trenches and small rock-cut shelters that can still be seen and touched.

The hill 402, so called in military jargon for the fact of being at 402 meters above sea level, is a recently recovered space, an area articulated around a hill north of Corbera de Ebro that served as the command post of the 35th Division of the People’s Army of the Republic during the first days of the Battle of the Ebro, when it was about to conquer Gandesa.

We must talk about the Coll del Moro. Continue on Nacional 420 towards Calaceite and take the exit at 7.8 kilometers (signage Poblat Ibèric). Here during the Spanish Civil War General Franco located his headquarters to direct the strategy of the Battle of the Ebro.

Do not forget the Camposines Memorial: In the direction of Mora de Ebro by the national 420 and turning left towards Flix at 6.6 kilometers. Follow direction Flix and just at 800 meters turn right (there is a sign Memorial de les Camposines). This memorial, built on a former Civil War trench, is a memorial to the missing combatants. Here are deposited the bones that, still today, appear in the scenarios of the Battle of the Ebro.

The surface of the ground oozes history, but only for those who want to see it.
