1. Nertóbriga.
Fregenal de la Sierra. Badajoz. SPAIN.
The first occupation of the site dates back to Roman times. The existence of a population living on the Coto's Hill before to the Roman conquest has always been deduced from the same city name, composed of two terms of clearly Celtic ancestry, 'nerto' with the meaning 'strong' and 'briga' 'city'. By extension, 'fortified town'.
Nertobriga is mentioned in the classics, Greek and Latin sources, as a population of Beturia Celtic, Lusitanian region in the southwest of Extremadura and border with turdetano- tartesio world and subsequently incorporated by Rome to its Andalusia province. Ptolemy provides its geographical coordinates; Polybius mentions the city about his decision to take the city by Roman troops under the command of Marco praetor in 152 BC
