The term "Arab-Norman" refers to a unique cultural and architectural blend that emerged in Sicily during the 11th and 12th centuries. This period followed the conquest of the island by the Normans, who were influenced by the existing Arab culture, which had thrived in Sicily for several centuries. The resulting fusion is evident in various aspects of life, including art, architecture, and language. Arab-Norman architecture is characterized by its intricate designs, featuring elements such as horseshoe arches, mosaics, and decorative tile work. Notable examples include the Palatine Chapel in Palermo and the Cathedral of Monreale. This rich cultural heritage reflects the coexistence and collaboration of different civilizations on the island.
