Notre-Dame de Paris ( meaning “Our Lady of Paris”), also known as Notre-Dame Cathedral or simply Notre-Dame, is a medieval Catholic cathedral on the Île de la Cité in the fourth arrondissement of Paris, France. The cathedral is widely considered to be one of the finest examples of French Gothic architecture, and it 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. This cathedral today welcomes more than twenty million visitors a year (including fourteen who enter the cathedral). It celebrated in 2013 the 850th anniversary of its construction.
