Notre-Dame de Paris is a medieval Catholic cathedral on the Ile de la Cite in Paris, France. The cathedral is widely considered to be one of the finest examples of French Gothic architecture, and is among the largest and most well-known church buildings in the world. The naturalism of its sculptures and stained glass are in contrast with earlier Romanesque architecture.
