In Catalonia, 130Km from Barcelona, near the town of Arbeca, we can visit the remains of an Ilergetian fortress built 2800 years ago, an exceptional historical and archaeological complex, one of the most important in southern Europe during this period. The excavation works started on 1985. In that moment, the archaeologist’s work date what they found on the year 325 B.C. and they discovered a ruins from a civilisation with architecture and urbanism knowledge, a ruins that tell us the history of a group of persons that knows about agriculture and farmer, but in the first stage of the iron era. This village was inhabited for 400 years. They built walls, towers, houses, furnaces, squares and streets, all encircled by a wall that protect them from the enemies. The fortress has a single gate. Since 1985, the Fortress of Vilars has been the reason of reunion, year by year, of a group of people, archaeologists and volunteers, that continue to explore this place.
