What region was the center of moorish culture on the iberian peninsula?

The region that was the center of Moorish culture on the Iberian Peninsula was Andalusia, in southern Spain.

Explanation:

Andalusia, which has its name from the Arabic "Al-Andalus", which was the name given by the Moors to the Iberian Peninsula, was the epicenter of the Muslim conquest of that peninsula. From the city of Cordoba, located in that region, Al-Andalus, formally the Caliphate of Cordoba, was organized. Today, cities such as Seville, the mentioned Cordoba, Granada, Cadiz and Malaga, among others, show Muslim influence both in its architecture and in its gastronomic and musical expressions. Likewise, a large percentage of its populations possess a certain degree of Moorish heritage.
