Vilalba dels Arcs (in Catalan; Valencian pronounced as /biˈlalβa ðelz ˈaɾks/) is a municipality in the comarca of Terra Alta in Catalonia, Spain.
This town is located in a wine-producing area.[3] The area suffered much during the Battle of the Ebro. At the site known as Els Barrancs there are still almost intact trenches of the Spanish Republican line of defence, part of a long defensive line built between Vilalba dels Arcs and La Pobla de Massaluca.
