What is "acinipo"

Acinipo was a city created by retired soldiers from the Roman legions more than 2,000 years ago, about 20 kilometers from Ronda, near Seville, Southern Spain. The Acinipo ruins include a Roman theater still in use today. Acinipo is known locally as Ronda la Vieja, Arunda or Old Ronda, though it has a separate origin and history from Ronda.
