Notre-Dame de Paris (French: [nɔtʁə dam də paʁi] (About this soundlisten); meaning "Our Lady of Paris"), referred to simply as Notre-Dame,[a] is a medieval Catholic cathedral on the Île de la Cité in the 4th arrondissement of Paris. The cathedral was consecrated to the Virgin Mary and considered to be one of the finest examples of French Gothic architecture. Its pioneering use of the rib vault and flying buttress, its enormous and colourful rose windows, as well as the naturalism and abundance of its sculptural decoration set it apart from the earlier Romanesque style. Major components that make Notre Dame stand out include one of the world's largest organs and its immense church bells.
