Beginning with the eighth-century defeat of Islamic forces in the Asturian mountains, this program traces the gradual return of Christian rule to Spain. Breathtaking depictions of World Heritage sites guide viewers along the Route of Santiago de Compostela—a Christian pilgrimage that catalyzed the struggle against Islamic control—as well as strategically important cities, including Toledo, Avila, and the last Muslim stronghold to fall, Granada. The historical narrative explains how smaller kingdoms merged to form more powerful unions, leading to the alliance of Castille y Leon and Aragon and, ultimately, the creation of a single Christian nation.
