Coin is situated in the fertile valley of the rio Grande approx 21 Km inland from Marbella and there is little doubt that a community of some kind existed on the spot long before the Roman conquest. The coastal mountains meet the Guadalhorce Valley between the cork oak and pine woods of Alpujata de Coin. According to archaeological finds made in the Cerro del Aljibe area of Coin, people have lived here since the first century B.C. Tombs and ceramic pieces found in the Llano de la Virgen area show evidence of a medieval settlement in the area, although we know the Romans stopped off here too. They named the place Lacib-is, later changing it to La Cobbin and finally setting on Castro Dacuan. From this last name, it is thought, the name Cohine derives. The name Castro, nevertheless, makes us think of some social structure or base of what is now Coin. It was the Moors who began to build the town that now stands, making it one of the most important in the region. Abderraman III raised the defensive walls over the remains of the ancient Roman settlement.
