Three-part series exploring the Baroque tradition in many of its key locations. Starting in Italy and following the spread of the wildfire across Europe and beyond, art critic Waldemar Januszczak takes us on a tour of the best examples of Baroque to be found, and tells the best stories behind those works. He follows Baroque to its dark heart in Spain, focusing on the route of the pilgrimage to Santiago de Compostela and featuring star painters Velasquez, Caravaggio and Zurburan. He then carries on through Belgium and Holland to discover such celebrities as Rubens and Vermeer.
