Guided tour of the last defense of the Republic during the Civil War at Coll de Balaguer. On this walk we can visit from concrete bunkers where Republican soldiers could have unloaded their machine guns on the national enemy, to shelters for troops and powder magazines for ammunition. Where the smell and fervor of war could have covered these landscapes of sea and mountains all connected by meters and meters of majestic trenches and military runways. You can put yourself in the shoes of Republican soldiers seeking protection from air raid bombs and artillery attacks, resisting in the last line of defense of Coll de Balaguer, do you dare to relive history?
