The audio guide tells the story, describes the architecture and reports interesting facts about the church. In 1072 Norman Dukes conquered Palermo and, in Sicily, began an era in which the Byzantine culture, the knowledge of the Arabs and the expressiveness of the Normans fused, creating an extraordinary unity. The symbol of this synthesis is the church of Santa Maria dell'Amiraglio, better known as "la Martorana". It was made in 1143. The audioguide has been made by professionals in the field of history and art.
