Acinipo

Acinipo was a city about 20 kilometers from Ronda, in the Spanish province of Málaga, 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. It is sometimes referred to as Ronda la Vieja despite the fact that Acinipo and Arunda co-existed for centuries.
