Critic and art historian Andrew Graham-Dixon travels from southern to northern Spain to tell the story of some of Europe's most exciting and vital art. For 700 years, most of Spain was an Islamic state and the south was its beating heart. Under the Moors, Spain became the most advanced, wealthy and populous country in Europe. Graham-Dixon travels to Cordoba, Seville and Granada, visiting beautiful Moorish palaces and mosques, telling the story of one of the most colourful and sophisticated cultures to ever appear in Europe.
