Travel through the most historic regions of northern Spain. Follow in the footsteps of ancient Phoenicians, Carthaginians, Greeks, Romans and Moors—peoples who once called this land home and who left behind extraordinary vestiges of their presence. All contributed to the rich traditions and colorful culture of modern Spain. This special program begins in cosmopolitan Madrid and also features five UNESCO World Heritage List sites: the old towns of Segovia, Ávila and Salamanca; Burgos Cathedral; and the architecture of Antoni Gaudí in Barcelona.
