The region was already inhabited in the prehistory. There are a number of caves that served as a shelter for paleolithic men in the Montgrí Massif, the most famous ones share the same name: “Cau Del Duc”, one in Torroella and the other in Ullà. We also find important megalithic structures in Massís de les Gavarres or Massís de Cadiretes, as well as the dolmens in Fitor.
The Greeks established themselves very close to the actual region, in Rhodes in the 8th century BC and in Empúries at the beginning of the 6th century BC.
The Iberians built one of their main cities in Ullastret in the 6th century BC; the name of the tribe was Indigetes. But with the arrival of the Romans, a process of transformation was initiated that changed the occupational system and the economic exploitation of the territory, which let to the abandonment of Ullastret in the 2nd century BC.
The Baix Empordà was Romanized like all other places of the Roman Empire but that was followed by barbaric invasions in the 3rd and 5th centuries that notably impoverished the region and reduced their urban centers to the minimum expression.
There are many traces of the Romanization, but it is hard to envision the print of the Visigoths and the Arabs, because the proximity of the Kingdom of the Franks caused the creation of independent counties ruled by feudal lords. The Musulman invasion actually lasted less than sixty years (714-785) and the old Hispanogothic population came back.
