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 historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
