During the Spanish Civil War, the Coll de Balaguer pass, located in our district, was considered a strategic vantage point for the Republican defence. A defence system was built here, made of trenches, parapets, machine gun shelters, powder magazines, shelters and other elements that were adapted to the landforms following the principles of fortification dissemination and occultation, taking advantage of the mountain pass’s perimeter.
These fortifications remained, in some areas, incomplete and, finally, they were never used for land-based attacks, because Franco’s military offensive was undertaken via the Battle of Ebro. After the Republicans’ defeat, these constructions remained abandoned. However, Franco’s marine staffs were planning a disembarkation operation at the L’Hospitalet de l’Infant beaches. The campaign’s quick end in Catalonia truncated the operation, while thousands of infantrymen and large sea squadrons were awaiting orders in Vinaròs and Sant Carles de la Ràpita.
