Acinipo was a city about 20 kilometers from Ronda, believed to have been founded by retired soldiers from the Roman legions more than 2,000 years ago. The remaining ruins include a Roman theater still in use today.
Some historians assert that Acinipo was created after the battle of Munda (45 BC), fought between the armies of Julius Caesar and the army of Pompey's two sons, Gnaeus and Sextus. To Caesar, Munda was supposed to be a mop-up action after Pompey's main forces were defeated in Greece. But Munda was no mop-up exercise. Tens of thousands of Romans were killed on both sides; there was no decisive victory for Caesar's armies; and one of Pompey's sons, Sextus, fled to fight another day as a famous rebel pirate against Caesar's successor, Augustus.
Some Spanish historians state that Munda is the Roman name for Ronda, where the battle of Munda may have been fought. According to Pliny, the battle of Munda was fought in Osuna, about 50 km north of Ronda in the province of Seville. But there is general agreement that Acinipo was created for retired veterans of Caesar's legions, while Arunda (Ronda) would be a separate Roman outpost, perhaps created before the Munda conflict for the veterans of Pompey's legions.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
