Leaving Seville, we headed north by train to Cordoba - a city dating to Roman times and in the 10th century was the most populous in the world as the center of education under the Islamic Caliphate. Cordoba was a stopover destination as we had booked the night's accommodation in nearby Granada. In contrast to the 'modern' cities of Seville and later destination of Malaga; we found that Cordoba and Granada retained more of its interesting historic architecture contrasting Western (Christian) and Eastern (Islamic) influences.
